Higher rank aerological risks in coal mines

The steady trend of complication mining and geological factors in underground coal at the same time processes intensification cause growth dynamic manifestations natural mining, such as sudden gas outbursts, rock bursts, collapses, leading to dust explosions fires. This requires developing models different phenomena manifestation risks, which enable improving process safety a enterprise. In this study, based on methodology aerological risk assessment mines, structural analysis risks was carried out. criteria hazard mining-geological mine engineering vulnerability schemes methods ventilation, ventilation facilities, main fans were developed. A hierarchical structure higher ranks presented allows determining area superposition hazards systems for each its individual well quantifying these areas form risks. ranges values super-category mines hazardous by outbursts modes established. enables forecasting reducing course designing, operation, liquidation, conservation mines.
