Detailed information



The analysis of accidents concerned with the aero/gas dynamics control in coal mines reveals inefficiency of the current methods available for prediction of air-and-methane mixture explosions, as well as for physical modeling and mathematical description of gas explosion hazards in coal mines. The methodical approaches to methane safety proposed by the Moscow State Mining University school are also valid for estimation of methane hazard in development and breakage headings. To this effect, it is required to develop a system concept of induced accident risk management in coal mining based on the accident risk modeling with respect to aerology and gas emission factor, as well as on the modeling of gas situation when forerunners of explosion hazard originate in mine air. The experimental and theoretical research has revealed and refined the new and current mechanisms of methane flow in coal and host rock mass. This allows developing a theoretical framework for the technologies aimed to reduce air/methane mixture explosion hazards and to isolate explosion consequences, as well as enables designing bundled software for air and gas monitoring in coal mines with regard to effects of geotechnical processes during high-performance longwall operations.
