摘要
曙光煤矿为煤与瓦斯突出矿井,为消除煤巷掘进期间瓦斯突出的危险,设计采用底抽巷穿层钻孔预抽瓦斯技术进行区域消突,通过在1232运输巷现场试验,并采用钻屑法验证了底抽巷穿层钻孔预抽煤层瓦斯消突技术的有效性,成功实现了1232运输巷的安全高效掘进。
Shuguang coal mining for coal and gas outburst mine,to remove the danger of gas outburst during the period of excavating in coal roadway,drainage design USES bottom wear layer drilling technology of drainage gas in regional outburst elimination,through field experiment in 1232 transport lane,alley pumping and cuttings method is used to validate the bottom layer of borehole drainage effectiveness of coal seam gas outburst elimination technique,succeeded in 1232 the safe and efficient transportation lane tunneling.
