针对任楼煤矿Ⅱ7214、7258综采面实际情况,通过分析工作面的瓦斯主要涌出来源及涌出量,结合任楼煤矿Ⅱ1、中五采区通风系统及瓦斯抽放系统现状,因地制宜的制定合理瓦斯综合治理方案。采用底板穿层钻孔与工作面顺层钻孔卸压抽放、高位走向钻孔抽放、上隅角站管抽放、优化抽放、通风系统等瓦斯治理技术;根据瓦斯来源不同,抽放浓度、流量差异较大,采取高浓低流、低浓高流分源抽放,取得了很好的治理效果,真正的实现了综采面的高产高效。
In view of the actual situation of Ⅱ7214 and 7258 fully mechanized mining face in Renlou Coal Mine, by analyzing the main sources of gas discharged from the working face and the emission, combined with the status quo of the ventilation system and gas drainage system in Ⅱ1 and S5 areas in Renlou Coal Mine, Rational gas comprehensive management plan. Adopting the technology of gas drainage technology such as floor penetrating borehole drilling and pressure relief drainage along the working face along the borehole, high-level drainage to the borehole, station drainage at the upper corner, optimization of drainage and ventilation system, etc. According to different sources of gas, Put the concentration, the flow is quite different, to take high-concentration low-flow, low concentration and high-pressure source drainage, and achieved good governance effect, the real realization of the high yield and efficiency of fully mechanized face.
