摘要
以神东矿区的保德煤矿为背景,根据高瓦斯矿井瓦斯防治和防灭火需要,通过改进采空区抽放、优化工作面通风系统、注浆注氮等综合防灭火技术,使工作面上隅角瓦斯得到有效治理,避免了采空区火灾事故的发生,有效解决了工作面瓦斯治理和防灭火问题,确保了81306工作面的安全回采。
Combining with the engineering background of Shendong Baode coal mine,according to the requirement of gas prevention and fire control in high gas coal mine,through the improvement of goaf gas drainage,optimization of ventilation system in working face,and application of comprehensive fire control technology such as grouting nitrogen injection,the gas in upper corner has been effectively controlled,which solves the problems of goaf fire control,as well as gas and fire control in the working face,ensuring the safe mining of 81306 working face.
