INTRODUCTION Nowadays, the world coal industry is nearly the most difficult sphere of economic activity from the point of view of an assessment and realization of prospects of its further development. Such situation, on the one hand, is caused by the in- creasing role, weight and economic feasibility of alterna- tive energy sources implementation. Already more than 30 countries of the world have proclaimed that they have reached smaller costs of their usage in relation to tradi- tional sources on the basis of coal, oil and gas and even nuclear power. It leads to the fact that the governments are skeptical about necessity of the state support of the coal- mining enterprises and providing any preferences to them. On the other hand, the industry continues to provide millions and millions of work places not only at the enter- prises, but also in partner spheres, such as metallurgy, me- chanical engineering, chemical industry, etc. Besides, in- creased investments into technological development of the enterprises connected with complication of mining-and- geological conditions of coal mining from year to year. Presence of such multidirectional vectors of economic pressure leads to necessity of acceptance by the enterprises of measures for prevention of threats for steady functioning. V. Bondarenko, V. Cherniak, F. Cawood, V. Chervatiuk. (2017). Mining of Mineral Deposits, 11(2), 1-11 2 In domestic practice it is necessary to add to these fac- tors also political one, which consequence of action viola- tion of integrity of the organizational and economic mech- anism of management of industry and coordination of work of the state and private sectors of coal mining has turned out. In such conditions, so far, only the Donbass Fuel and Energy Company (DTEK) keeps perspective technical and technological base for improvement organi- zational and economic making productions of coal output. For the last 11 years, Company invested nearly UAH 20 billion in development of mines (Derun, 2016). Since 2013, on DTEK enterprises the system of eco- nomical production “Innovator” based on rules of the Toyota production system (Toyota Production System – TPS) which principles and tools have found reflection in its American option – system of economical production of LEN (LEN – Lean Production). Its represented as a certain complex of actions for management of the organization which are directed on improvement of quality of work due to reduction of losses. And even in a year of implementa- tion, the effect of introduction of “Innovator” at the DTEK coal enterprises has made only UAH 8.2 million, then in the next years it has considerably increased, and in 2014 has reached to UAH 66.6 million, and in 2015 has ex- ceeded the amount of UAH 270 million. For today, statis- tically, each 20 minutes in DTEK the new idea on ensur- ing lean manufacturing is suggested. However, the system strategy of maintenance of com- petitiveness and development of the coal-mining enter- prises can be constructed only on a strong scientific and methodical basis (Kharlamova, Nate, & Chernyak, 2016). Such scientific approaches to increase in efficiency of ac- tivity of the enterprises urgent today as “concept of sus- tainable development of the enterprise” and “concept of economic security of the enterprise” can make its concep- tual basis of construction (Vorotnikov, 2014). At the same time, it is necessary to consider that mining industry has certain specifics of activity which are available dynamic working space that imposes certain restrictions for usage of classical scientific approaches to ensuring sustainable development of the enterprises. The attention was already focused on the fact that en- terprises of coal industry have specific conditions which can influence on functioning of safety mechanism of sus- tainable development. Works that devoted to enterprises of mining and metallurgical complex (Slobodchikova, 2016; Amoosha, Starichenko, & Cherevatskyi, 2013; Dhookie, 2016) are testified about that. The attention of the last research on this issue con- centrates generally on economic and financial aspects of stability of the coal enterprises, and “technology”, though is noted as a significant factor, but remains be- yond the scope of research. Furthermore, for instance, in work of Trifonova (2015), concentrating on a perspective of “stability of the enterprise” and “stability of function- ing of the enterprise” (including coal mines), researchers let go that as it has been shown above, these phenomena can be considered only as the separate moments of “sus- tainable development of the coal enterprise” and can’t be considered as the complete business strategy of the en- terprises of coal industry. Weighing features of functioning and development of the coal enterprises and considering the level of scientific developments on the designated perspective, it is possi- ble to note that the special attention is required by a tech- nological component of safety of sustainable develop- ment today. 2. PRINCIPLES OF ADAPTATION PROGRAMS FORMULATION OF COAL MINES DEVELOPMENT Any operating mining enterprise and coal mine in par- ticular, represent the difficult dynamic system that func- tioning in continuously changing conditions of the internal and external environment. For instance, volumes of daily updates of working space on stoping and preparatory mine workings on coal mines of DTEK in 2016 exceeded 60 000 m3 (Fig. 1), i.e., every day cardinal transformations of space of 5 football fields on height in human growth were undergo. Figure 1. Changes of working space on DTEK coal mines Advance of the front of stoping and preparatory oper- ations, displacement of roof and bottom rocks, changes of gas-and water abundance of mine workings – all these lead to necessity of ensuring stability of functioning and devel- opment of the enterprise and, respectively, development and implementation of projects (programs) that allowing to create such maintenance. Furthermore, it is necessary to consider instability factors that connected with the level of readiness of stocks for application of these or those tech- nological schemes. According to Khetagurov (2013), min- eral reserves which are initial product of the nature, have significant effect on overall performance of the rock en- terprise for this reason: – have no starting cash value in its classical sense; – placement and total number of resources (category A, B, C1 and C2) in subsoil have various degree of a prob- abilistic assessment; – in each time point, the assessment of deposits stocks is confirmed by data of the reconnoitered part of stocks, and the information about them is replenished with expan- sion of its industrial development; – resources of minerals are non-reproducible, and at the same time can be filled up due to geological investigation; 111276 113224 62962 48834 51277 11158 14625 15885 10135 9593 2 0 1 2 2 0 1 3 2 0 1 4 2 0 1 5 2 0 1 6 DTEK stoping DTEK preparatory V. Bondarenko, V. Cherniak, F. Cawood, V. Chervatiuk. (2017). Mining of Mineral Deposits, 11(2), 1-11 3 – the constant preparation of the new front is necessary for providing a continuity of production drivage of perma- nent and preparatory mine workings, operations on sup- porting of mine workings, construction and equipment of transport communications and so forth; – initial expenses on preparation of the new front con- ducting is very essential and demands a considerable ad- vancing in time of mining operations; – fields and their sections are characterized by very various conditions of a bedding and quality of minerals and, as a result, efficiency potential; – the infrastructure of the enterprise including a complex of buildings and constructions in the absence of effective re- serves of mineral, and practically, has no market value. Basing on analysis of industry specifics of activity, it is possible to predict with confidence that for coal mines in such ways of development today is increasing in adap- tive abilities of the enterprise to mining-and-geological conditions of development of deposits and research of technical-and-technological capabilities of ensuring ex- panded reproduction. The comprehensive programs of adaptive management including a retrospective and perspective assessment of a trajectory of development of mining enterprise, identifica- tion of critical stages, dangers, risks, emergency situations which can change the developed tendencies, form a basis of such work and create the innovative potential of ensur- ing safety and steady functioning. Set of interrelations of properties and opportunities of the developing objects, their parametrical reflection also makes a structural and logical basis (Fig. 2) of adaptation programs for the mining enterprises reproduction. ъ Figure 2. Structurally-and-logical scheme of programs elements interaction of adaptive management on coal mines Problems of adaptability, adaptation process, adaptive management of the enterprises are subject to close atten- tion of scientists. At different times in the context of de- velopment of the enterprises, such authoritative foreign scientists as D. Andresen, I. Ansoff, J. Dixon, P. Segne, A. Setkhi, and S. Setkhi, V. Stephenson who have laid the theoretical and methodological foundation of the concept of adaptive management of the enterprises were engaged in such tasks. Usage of the basic principles of programs of adaptive management of technological processes on DTEK mines within such actions have allowed to reduce necessary volumes of updates of working space almost twice (Fig. 3), reducing thereby potential area of critical activ- ity and increasing technological safety of production. And if in 2012 – 2013 practically the same volume of mined rocks fell on each cubic meter of the extracted coal, now it was reduced almost by 3 times (Salli, Ma- maykin, & Smolanov, 2013). The cumulative effect from realization of innovative actions on Ukrainian coal mines of DTEK during the pe- riod from 2013 to 2016 has made about UAH 480 million that at the cost of “start” of one longwall of UAH 50 mil- lion, it corresponds to economy of commissioning of 10 stoping faces.

Efficiency of implementation of adaptation programs of stoping and preparatory operations technology in conditions of DTEK mines (daily renewals of working space on 1 ton of extracted coal, cubic meters) At the same time, it is necessary to consider what con- sequences of the entered innovations can exert negative im- pact on balance of safety and stability. Such influence not always happens obvious, especially if the indicators that characterizing adaptability weren’t considered in advance and borders weren’t projected in calculations, and borders or scale of values of its level are also not developed. For prevention of negative consequences of such plan, on the basis of the analysis of theoretical and me- thodical base of a research of adaptation processes and the phenomena in functioning of the enterprises, the fol- lowing complex of requirements (A) and principles is proposed (B), on the basis of which adaptation programs of development of coal mines have to be formed (Chernyak, 2004): A. Adaptation programs of coal mines development has to meet the following requirements: – to have the high flexibility allowing to change quickly; – to have high mobility in adoption of administrative decisions and their realization in life; – to be an adequate to current situation; – to consider the serious competition; – to consider requirements for professionalism level; – to consider the risks that connected with dynamics of changes and development; – to take into account necessity of uncertainty of the external environment; – to predict transition of system from one state in another by a preliminary task of parameters of external environment; B. Adaptation programs of coal mines development has to be based on the following principles: – system-wide principles; – methodical principles; – principles of the structural organization of adaptive business management; – principles of an indicativity and measurability; – the special (industry) principles that determined by specifics of the concrete enterprise activity. In particular, for coal mines one of the basic principles can be considered the principle of restriction of working space updates. Realization of this principle in practice can be reached due to reuse of mine workings and, respec- tively, increases in stability of those mine workings which can be potentially reused, and also by increase in length of extraction pillars that provides increase in concentration of stoping operations. Further research of considered per- spective also have to develop in the direction of a specifi- cation of the special principles of development of manage- ment adaptation programs of safe and sustainable devel- opment of coal mines. In conditions of mining enterprises, technical-and- technological environment is the most quickly changing element that gives the foundation to consider technologi- cal processes as a basis of formation of safe and sustaina- ble development. 3. METHODICAL FEATURES OF ADAPTATION PROGRAMS ELABORATION OF COAL MINES DEVELOPMENT Having considered basic elements of conceptual base of sustainable development of coal-mining enterprises and ensuring its technological safety, we can pass to statement and solution of the first analytical task: to analyze and es- timate specifics of parametrical, algorithmic and resource adaptation of technological system of coal mines. Difficulty of the solution of such task consists in vari- ous conditions of production of underground operations because of insufficiency and uncertainty of information on true parameters of the massif outside mine workings, real indicators of mining operations can significantly differ from planned (design). Problem statement. We have the changing Technolog- ical working space of TWS representing the interacting complex of two Technological subspaces (Fig. 4): – technological subspace TSS1 of stoping operations; – technological subspace TSS2 of preparatory operations. Figure 4. Technological subspaces Changes TSS1 and TSS2 happen within plan targets. At the same time, the actual resultant values of changes are fixed as in positive (a plan overfulfillment), and in neg- ative (failure to follow the plan) ranges of the arising sets of events. Both unforeseen combinations of conditions and mistakes in administrative decisions can be the rea- sons of existence of zones of non-performance of plan tar- gets: or in aspect of establishment of the plans which aren’t corresponding to the current conditions or owing to using not rational technology of mining operations con- ducting. The solution of a task, in broad understanding, is minimization of probability of manifestation of events in the negative range. The choice of schemes and the sequence of updating of technological working space, and also temporary char- acteristics of each work (beginning, termination, duration) and determined by appointed (planned) intensities of their performance which in the maximum measure correspond to conditions of the environment of TSS1 and TSS2 is the result of solution of an objective. 1.27 1.13 0.78 0.75 0.75 0.00 0.20 0.40 0.60 0.80 1.00 1.20 1.40 2012 2013 2014 2015 2016 ТSS 1 Т S S 2 V. Bondarenko, V. Cherniak, F. Cawood, V. Chervatiuk. (2017). Mining of Mineral Deposits, 11(2), 1-11 5 For reflection of qualitative “picture” of examined task conditions and results of work of the operating coal mines of DTEK during the period from 2012 to 2016 are consid- ered. As the dynamic indicator of a situation, the interre- lation of speed of stoping and preparatory mine workings with performance of plan targets is analyzed. The statisti- cal set displaying this interrelation is presented on Figure 5. In general, these works of 1125 drivage and 478 stoping faces (Table 1) have been processed. For finding solutions of problems of this type it is re- quired to create a technique of a research of ways of providing economic (in aspect – technological) safety and stability of working space (TSS1 and TSS2) in conditions of its continuous change which in basic option comes down to a technique of the solution of a task of adaptive management of mining operations development and for- mations of the appropriate adaptation programs. Procedures of search of the adaptive decision (or adap- tive procedures) can be divided into three groups: proce- dures with parametrical adaptation, procedures with algo- rithmic (structural) adaptation and procedures with resource adaptation. The first group of procedures can be considered as a special case of the second – algorithms (structures) dif- fer only in values of the operated parameters. (a) (b) (c) Figure 5.

At the same time, model F which consists of structure and parameters is formed:  CStF , , (1) where: St – structure of model F; C = (C_1, ..., C_k) – its parameters. Such adaptive models function in the conditions of a multicriteriality, and these criteria can be not only ex- treme, but also have the nature of restrictions. It induces to formulate several criteria at once and to vary their choice depending on current situation and internal require- ments of the system. Thus, already the choice of criteria of adaptation is process adaptive and has to be considered during adaptation determining. Therefore, with taking into account features of difficult systems, adaptation is defined in a broad sense as process of purposeful change of param- eters and structure of system which consists in determina- tion of criteria of its functioning and performance of these criteria (Rastrigin, 1981). The main approach to the solution of this kind of tasks is application of expert methods of an assessment and sit- uation analysis (Kovalevska, Illiashov, Fomychov, & Chervatuk, 2012; Bondarenko, Hardygora, Symanovych, Sotskov, & Snihur, 2016). In the conditions of a multicriteriality of tasks it is ex- pedient to apply entropy approach to an assessment of sit- uations to increase in efficiency of adoption of expert de- cisions. For this purpose, data of any selection can be rep- resented in the form of Pareto-diagram, such as on Fig- ure 6 results of defragmentation of selection on effective- ness of TSS2 changes during using of continuous methods of preparatory mine workings are displayed. Further, we can calculate value of entropy within each fragment of the splitting received on diagram according to a formula: 1ln1   n i ii PPН , (2) where: n – the number of groups into which the schedule dur- ing calculating is divided; Pi – value of probability of point getting into a certain group. Figure 6. Total Pareto-diagram of data sampling of plan performance of preparatory mine workings during 2012 – 2016 On diagram on Figure 6, significant Pareto-area in- cludes 5 groups (ranges), the number of observations in which is equal to 81.4% of the total amount of selection (905 points of 1111 considered, data which correctness isn’t confirmed weren’t considered). Values of indicator of performance of plan targets in the range of values from 60 to 135% get into these groups. At the same time, if to analyze selection after a time interval (by years, from 2012 to 2016, Fig. 7), it is possible to see that significant groups in separate years can settle down in wider range therefore for the further analysis the settlement range of values of an indicator of implementation of the plan for preparatory mine workings drivage from 40% (at the minimum value of 38% in 2012) to 160% (at the maximum value of 152% according to 2012) is determined. Value of entropy on a total indicator of plan targets performance on preparatory mine workings drivage dur- ing 2012 – 2016 are defined on the basis of the calcula- tions that presented in Tables 2 – 4. From Figure 8 it is follows that the probability of plan targets performance on preparatory mine workings drivage on DTEK mines dur- ing 2012 – 2016 was equal to 50%. V. Bondarenko, V. Cherniak, F.

The schedule of probability of plan targets perfor- mance on preparatory mine workings drivage during 2012 – 2016 Range from 0 to 40% are characterized by the greatest uncertainty that confirms existence of weakly-predicted situations that connected with sharp deterioration in min- ing-and-geological conditions as follows from the sched- ule that submitted on Figure 9. Figure 9. The schedule of entropy values (uncertainty level) of plan targets on preparatory mine workings drivage The probability of approach of events of such plan is equal to 6 – 15%. And here almost equal values of en- tropy (uncertainty level) in the range from 40 to 100% of plan performance for a drivage reflects an incorrect as- sessment of a condition of technological space at the level of planning. And, respectively, the probability of failure to follow the plan as a result of such actions of managers is equal to 36 – 45%. For identification of the concrete reasons and defini- tion of preparatory operations necessary for transfor- mations of an algorithm of maintaining, it is necessary to conduct analysis of influence of separate mining-and-ge- ological and production factors. Similar procedures of the analysis are performed also for an assessment of a technological subspace of stoping operations. 4. CONCLUSIONS As a result of the executed analysis, it is established that concepts of “sustainable development” and “economic se- curity of the enterprise” are crossed in a set of definitions and factors which form and reflect their essence. Being guided by provisions of dialectic logic in a tandem these phenomena, it is possible to consider at the same time as process and as the mechanism of its providing. It, in turn, means that planning of stoping and pre- paratory operations demands optimization of analytical procedures and an assessment of structure and condi- tion of technological space of the enterprise. The re- quired algorithm of changes of technological working space has to: – provide performance of planned targets on volumes, types and quality of mine workings; – conduct strict spatial and temporary coordination of the planned works; – provide maintenance for technological sequence of changes of TSS1 and TSS2, not to allow its critical deviations; – provide continuous updating of TSS2 with taking into account regulated breaks in changes of TSS2; – provide planned loadings of mining sections in sub- critical limits. Adaptation activity at the enterprise always needs ei- ther in current, or perspective resources. Practical ability to conduct resource support of process of adaptation also reflects, in fact, a possibility of ensuring economic secu- rity of the enterprise. And as, in this case, the technologi- cal subsystem of the coal mine is considered, so we will talk about resource adaptation in aspect of process of tech- nological safety ensuring of the enterprise.
