Abstract: Here in the results of the analysis of the current state of the problem of the occurrence of endogenous fires during mining of coal seams in mines. The influence of mining and geological conditions on the efficiency and safety of mining seams prone to spontaneous combustion is considered. The need for an integrated approach to solving the problem of spontaneous combustion during mining in difficult mining and geological conditions is shown. The specific areas as well as factors of spontaneous combustion occurrence were identified. A classification of methods for predicting and localizing spontaneous combustion in coal mines is proposed, which includes three main groups: organizational and technological measures, measures to control and monitor the aerological situation of the mine panel, and methods for local prevention of the occurrence of spontaneous combustion hazard. On the example of mining a thick coal seam using the technology of top coal caving, as the most endangered fire hazard factor, technical and organizational solutions are proposed to improve the forecast of fires at the boundary of a mining site. They include expansion of the network of air-gas control sensors, chemometric analysis of the obtained data, collection and processing of the main technological parameters of the mine panel. Based on the obtained data, a forecast is made of safe technological parameters of the excavation site, taking into account the boundary conditions of chemometric monitoring.
