采空区瓦斯与煤自燃复合灾害防治机理与技术研究

Study on Prevention and Control Mechanism and Technology of Gas and Coal Spontaneous Combustion in Goaf

近几年随着我国煤矿开采深度的不断增加,瓦斯涌出量持续增大,瓦斯灾害变得日益严重;且地应力提升,煤岩的破碎量增多,以及地温提升,煤自燃灾害也开始展现出来。两种灾害共生的复合型灾害变成了目前煤矿重特大事故的核心模式。因此,针对采空区瓦斯以及煤自燃复合灾害的相关内容进行分析和总结显得十分重要。

In recent years,with the increasing depth of coal mining in our country,the gas emission continues to increase.Gas disasters are becoming more and more serious,and the crushing amount of coal and rock increases with the increase of in-situ stress.As well as the rise of ground temperature,the coal spontaneous combustion disaster has also begun to show.The complex disaster of two kinds of disaster symbiosis has become the core mode of serious and extraordinarily serious accidents in coal mines.Therefore,it is very necessary to analyze and summarize the related contents of gas and coal spontaneous combustion in goaf.
