摘要
文章介绍了顶板高位钻孔瓦斯抽采工艺及存在的问题,分析了顶板高位走向钻孔抽采效果的影响因素,并对任楼煤矿Ⅱ7212大采高综采工作面高位走向钻孔的设计、施工及抽采效果进行试验研究,优化任楼煤矿高位走向钻孔的布置参数,改进了钻孔的施工工艺,保证了矿井的安全生产。
The gas drainage process with high position borehole along roof and the existing problems were introduced, the factors affecting drainage effect were analyzed, and the experimental research were carried out, to study the design, construction and drainage effect of the Ⅱ 7212 fully -mechanized working face with large mining height in Renlou coal mine. The arrangement parameter of high position borehole along roof in Renlou coal mine was optimized, and the construction process of borehole was improved, ensuring the safety production.
