采空区自燃诱发瓦斯灾害耦合致灾特性及防控技术

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

为研究综放采空区瓦斯与遗煤自燃耦合灾害特征及危险区域,及时预防耦合灾害事故发生,研究了综放采空区瓦斯与遗煤自燃耦合灾害形成条件及特征。以山西和顺天池矿井301工作面为例,提出并实施了采空区煤与瓦斯火灾害监测监控、高抽巷抽采瓦斯及灌浆防灭火等协同防治技术,保证了工作面安全开采。

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.
