Ensuring the ever-increasing demands of society for energy resources is a key problem for the development of the economy of all countries of the world. At this stage, to improve the living and working conditions of a person, the development of industry and transport, the growth of production based on scientific and technological progress, a continuous increase in energy use is required. Analysis of the environmental consequences of coal mining shows that the human impact on the environment in the process of economic activity becomes global. Therefore, the main goal of the work is to assess the environmental safety in production because of a decrease in rock mass during underground coal mining. The work analyses the levels of negative environmental impact of coal industry enterprises. The relationship between the key statistical indicator that affects the accident rate and the value of professional risk is demonstrated. It is shown that despite the general tendency to reduce the number of cases of fatal injuries to coal mine workers, the procedure for assessing the risk caused by rock falls needs to be improved. In this regard, when assessing occupational risk, it becomes relevant to use information from multifunctional systems of safety (MSS). The complex method of effective control of mountain pressure is illustrated by application of the developed methodology of computer modelling of geo-mechanical processes, instrumental and geophysical methods for protection and maintenance of mine workings at development of a coal seam of the Barentsburg field.

To develop an effective model for assessing occupational risk due to rock caving in the country's coal mines. Methodology. A mathematical model based on the maximumlikelihood method is presented, which makes it possible to assess the probability of a rockfall. The use of Bayes theorem for assessing the individual risk of fatal injuries of coal mine workers is justified. The complex method for effective control of mountain pressure is illustrated by application of the developed methodol ogy of computer modeling of geomechanical processes, instrumental and geophysical methods for protection and maintenance of mine workings at development of a coal seam of the Barentsburg field. findings. The work demonstrates the relationship between the key statistical indicator that affects the accident rate and the value of professional risk. A key statistical indicator, the value of which is determined using the multifunctional systems of safety, is substantiated. originality. The development efficiency of the multifunctional safety system installation in coal mines to monitor the condition of the rock mass is analyzed. practical value. The model developed by the authors will make it possible to determine the predicted value of the individual risk of fatal injury to personnel during rock collapse more accurately compared to the existing methods.
