摘要:
潘三煤矿17181(1)运输顺槽顶板岩层含水丰富，下向穿层钻孔抽采17181(1)运顺瓦斯受岩层富水影响较大。为解决这一问题，结合潘三矿11-2煤顶板实际情况，分析了影响下向穿层钻孔抽采瓦斯的主要因素，提出了“先区域封水，后打抽采钻孔，再利用‘两堵一注’快速封孔法封孔”成套技术解决方案，形成了一种新型下向穿层瓦斯抽采钻孔封孔方法。经潘三矿17181(1)瓦斯综合治理巷现场实践证明，下向穿层抽采钻孔的瓦斯抽采纯量与抽采浓度均有大幅度提高，钻孔封孔效果良好
Abstract:
The roof strata of 17181(1) cross heading in Pan San coal mine contains water richly, for this reason, the gas is difficult to be extracted from the coal of 17181(1) cross heading through downward crosslayer drilling. In order to solve this problem, with the practical situation of roof strata of 112 coal seam in Pan San coal mine, the major factors influencing gas drainage through downward crosslayer drilling were discussed. A package solution contains plugging water in area and a hole sealing method was put forward, and a new hole sealing method for gas extraction by downward crosslayer drilling was formed. According to the field practice, this new method worked well, both the average quantity and the average concentration of extracted gas increased dramatically.
