Analysis of accidents and development trends in aerological safety of coal mines

Over the past few decades, there has been a tendency in coal mines to reduce the number of accidents and occupational injuries, however, those accidents that periodically occur are characterized by the simultaneous death of a large number of workers, which requires the concentration of scientific and industrial efforts to assess, predict and reduce the aerological risks of accidents in coal mines. The article presents the results of the analysis of accidents and injuries, the main causes of rock collapses, explosions of methane and coal dust, methane flares and ignitions, sudden emissions of coal, rock and gas, rock impacts, endogenous and exogenous fires in coal mines, analysis of the ventilation condition of coal mines. The distribution of the number of gas and dust explosions in coal mines according to ventilation schemes and methods is presented. The dynamics of the average daily load on a complex mechanized face is given. The methodology for ensuring the environmental safety of coal mines is based on a risk-based approach that takes into account the mining, geological and mining conditions of coal seams. Algorithmic support for calculating and reducing the aerological risks of accidents makes it possible to predict aerological risks and determine the directions of technical, technological, organizational and technical measures to improve aerological safety, while developing a safety justification, it allows to form a list of the most significant accident risk factors.
