Coupling Disaster Characteristics and Prevention and Control Technologies of Gas Disasters Induced by Spontaneous Combustion in Goaf

To study the characteristics and hazard areas of coupling disasters induced by fully mechanized caving goaf gas and residual coal spontaneous combustion, and to timely prevent the occurrence of coupling disaster accidents, the formation conditions and characteristics of coupling disasters induced by fully mechanized caving goaf gas and residual coal spontaneous combustion is studied. Taking 301 working face of Shanxi Heshun Tianchi Mine as an example, the collaborative prevention and control technologies including fire disaster monitoring for goaf coal and gas, gas drainage of high level drainage roadway and fire preventing and extinguishing technology by grouting are proposed and implemented to ensure the safety of the working face mining.
