摘要：Coal and gas outbursts are one of the most serious disasters in coal mining, and disaster prediction and prevention alarms are key technologies to prevent coal and gas outbursts. This paper summarizes the progress of research on outburst prevention alarm indicators and prevention alarm technology for mines; the mechanism of coal and gas outbursts; the relationship between the coal seam geological environment and outbursts; and the relationship between coal seam gas drainage, roadway excavation and mine working face (DEM) operations and outbursts. Prevention alarm indicators are key to effective prevention alarms. The analysis proposes that from the perspective of understanding the relevant theoretical research and the effectiveness, timeliness and comprehensiveness of the prevention alarms, there are still some deficiencies, and establishing preventive alarm indicators and preventive alarm models is difficult. Assuming the reasonable management of coal seam DEM, the coal seam geological environment is established as a secondary indicator. Production, gas drainage, ventilation, monitoring and control, auxiliary production and other systems are the third-level indicators. Catastrophic parameters such as safety distance, pre-extraction time, mining procedures and DEM replacement are used as fourth-level indicators for the outburst disaster risk assessment index system, which provides a basis for understanding mine risk decision-making and disaster prevention and alarms.
