“…The use of fuel coal in thermal power plants seriously affects the environment, with all its 278 different impacts, and this is the monthly cause (Kobylkin and Musina, 2019) of more than 7 million premature deaths in the world: from lung cancer (29%), acute respiratory infection (17%), stroke (24%), ischemia (25%), chronic lung disease (43%).…”

In today's economy, it is necessary to explore the environmental impact of mining. Coal mining greatly affects all environmental parameters of the environment: home, production, hydrodynamics. The environmental situation in the area of the mining company can be changed if environmental contamination is monitored and environmental protection plans and measures are developed. The purpose of this work is the analysis of systems and models of these processes in the ecosystem. The main systemic hypothesis of the research is that the variety of criteria and methods of risk assessment is a necessary condition of order in the system. The main results of the work are the following: 1) a systematic analysis of the problems of environmental security, geodynamics of the mining areas, aspects of the balance of the sustainable process and the cause of the increase in danger was carried out; 2) Proposed approaches (models) for the assessment of evolutionary ecological potential and health risks, as well as adaptive situational modeling of the ecosystem. It is important to note, the study results do not suggest complex environmental monitoring studies.

The paper develops the concept of the existence geodynamically dangerous zones in the earth’s crust. These zones affects to the safety of the state of engineering structures and mining operations. The concept of geodynamic zoning is used, according to which geodynamically dangerous zones occurs during the interaction of blocks of the earth’s crust of various hierarchical ranks. On the example of the East Donbass, the typification of the intersection of coal waste dumps with geodynamically dangerous zones is considered. The position of 34 burning and burnt out dumps located near the cities of Shakhty and Novoshakhtinsk, Rostov Region, their size R and the width of geodynamically dangerous zones r are taken in account. Based on the use of geodynamic zoning data, an analysis is made of the nature of the mutual arrangement of carbon rock dumps and the boundaries of blocks of the earth’s crust (geodynamically dangerous zones). It is found 4 types of intersection of the block boundaries and the body of the dumps. The intersection of the first type occurs when R> r and the location of the intersection site entirely under the dump. The intersection of the second type occurs when R <r and the location of the dump entirely in the geodynamically dangerous zone. The intersection of the third type occurs at any ratio of R and r, but the common area overlaps the geodynamically dangerous zone only partially (touch). In the fourth type of intersection, the set of common points R and r is empty (do not intersect). Typification can be used when choosing places for dumping and computer modeling of their thermal state.

At present, in the Russian Federation there are no legislatively approved recommendations on the procedure, structure and requirements for the design of an emergency response plan for coal open-pit mines. Therefore, the development of this document at the mining enterprises is carried out independently, coordinating it with emergency response services serving the hazardous production facility. The absence of regulatory documents forces the enterprise management to make decisions on the structure of the document, forms and its content. This can lead to errors in conducting mine rescue operations when attracting additional forces and means from other units of rescue units. The relevance of creating a single document for everyone to draw up a plan for the elimination of accidents at sections has been repeatedly noted at production meetings with the participation of scientists, specialists from surveillance services and representatives of rescue units. In order to increase the emergency preparedness of enterprises, on the basis of studies of the current regulatory documentation of Rostechnadzor, the EMERCOM of the Russian Federation, Mines Rescue Service and scientific literature, an algorithm was developed for compiling submarines for coal open-pit mines. The analysis of accidents at the coal open-pit mines of the country made it possible to create a list of types of accidents encountered. Based on this, instructions have been developed for the actions of all workers in the mine for the initial period in the event of an accident. Taking into account the existing standard forms for coal mines, the developed document forms for open pits were developed, this will make it possible to unify emergency rescue operations regarding the preparation of documents. Scientifically sound solutions can be used to develop a plan for the elimination of accidents in the future at all mining enterprises engaged in open mining. The results of the work expand knowledge in the field of safety of coal open pit mining.
