摘要
煤矿在我国经济高速发展中起着重要作用,但是在生产中时常出现安全事故。近年来,顶板事故频出,在采掘作业中遇到坚硬顶板时,顶板悬顶面积大,易造成人员伤亡。鉴于此类情况,为达到安全高效生产的目的,针对赤峪煤矿C1203回采工作面回风巷开展了二氧化碳致裂强制放顶技术研究,以有效解决高瓦斯矿井采空区悬顶面积大的问题,为类似矿井提供借鉴。
Coal mines play an important role in the rapid economic development of China,but safety accidents often occur in production.In recent years,roof accidents have occurred frequently,when a hard roof is encountered in min⁃ing operations,the suspended roof area of the roof is large,which is likely to cause casualties.In view of this situa⁃tion,in order to achieve the purpose of safe and efficient production,the research on the forced roofing technology of carbon dioxide fracturing has been carried out for the return airway of the C1203 working face in Chiyu Coal Mine,Ef⁃fectively solving the problem of large suspended roof area in the goaf area of high gas mines,and providing a reliable reference for similar mines.
