贺西煤矿2317工作面瓦斯治理以孔代巷技术研究

Study on Technology of Gas Control with Hole Instead of Roadway in 2317 Working Face of Hexi Coal Mine

本文以贺西煤矿2317工作面高位裂隙带钻孔为例,通过钻孔轨迹与抽采效果分析,不断调整优化轨迹参数,保证抽采效果,从而实现以孔代巷目的。工作面安全生产同时实现节能增效,形成了适用于贺西煤矿治理采空区瓦斯技术体系,有效降低了矿井瓦斯治理成本。

This paper takes drilling in high fractured zone of 2317 working face of Hexi Coal Mine as an example,through the analysis of drilling trajectory and drainage effect,constantly adjust and optimize the trajectory parameters to ensure the drainage effect,so as to achieve the purpose of hole instead of roadway.At the same time,the safe production of working face realizes energy saving and efficiency increasing,which forms a gas control technology system suitable for Hexi Coal Mine and effectively reduces the cost of mine gas control.
