| 摘 要： | 焦作矿区原有的底板抽采岩巷预抽措施，必须进行多次石门揭煤，严重制约了区域瓦斯治理进度。为解决这一问题，对该矿区演马庄矿21011运输巷进行顶板穿层钻孔优化，并对钻孔布置方式、孔间距等进行改进。结果表明，施工总量减少，施工进度加快，抽采效率显著提高，有效解决了区域瓦斯防突问题。

| Abstract: | The original pre-rock roadway floor drainage pumping measure of Jiaozuo Mining Area has seriously restricted the progress of regional gas control due to the rock cross-cut coal uncovering for many times. To solve this problem, actions have been taken to optimize the roof of borehole in the 21011 ore transportation roadway of Yan Mazhuang Mining Place of Jiaozuo Mining Area and to improve the hole arrangement, hole spacing, etc. The results show that it reduces the total process of construction, accelerates its speed, improves significantly the extraction efficiency and addresses the issue of regional gas outburst. |
