突出矿井掘进工作面瓦斯抽采技术研究

Study on Gas Drainage Technology of Heading Face in Outburst Mine

为解决突出矿井巷道掘进瓦斯因素的制约,实现安全高效掘进,通过煤层底抽巷实施穿层钻孔预抽煤层瓦斯、水力通孔造穴、工作面补充密集钻孔强化瓦斯抽采、巷道交替施工轮掘作业等措施,使掘进效率提高65%,达到安全高效掘进目的。

In order to solve the restriction of driving gas factors in outburst mine roadway and realize safe and efficient tunneling,measures such as pre-drainage of coal seam gas,hydraulic through hole making,reinforcement of gas drainage with dense drilling in working face and alternate construction wheel excavation of roadway are carried out through coal seam bottom roadway,so as to improve the tunneling efficiency by 65%and achieve the purpose of safe and efficient tunneling.
