阳泉矿区本煤层顺层钻孔标准化抽采研究与实践
|
摘要
阳泉矿区突出煤层顺层钻孔预抽瓦斯过程中长期存在钻孔瓦斯抽采浓度低、抽采量较小、抽采效率低等问题。为解决本煤层瓦斯抽采效果差的难题,阳煤集团开展了突出煤层顺层钻孔抽采标准化体系研究与实践,通过对钻孔设计、钻孔施工、钻孔勘验、钻孔封孔、钻孔连接、钻孔计量等抽采过程标准化系列研究和优化,实现了本煤层瓦斯高效抽采,有效缩短回采工作面抽采达标时间,对矿井抽、掘、采平衡和安全生产具有重要意义。
In Yangquan Mining Area,there are perennial problems in the process of gas pre-extraction of bedding drilling borehole such as low drilling extraction concentration,small extraction volume and low extraction efficiency. In order to solve the problem of poor gas drainage effect in the coal seam,Yangmei Group has carried out the research and practice on the standardization system of drainage of bedding drilling borehole in outburst coal seam. Through a series of research and optimization on standardization of extraction process,such as drilling design,drilling construction,drilling inspection,drilling and sealing,drilling connection,drilling measurement,etc.,the highly efficiency in gas extraction in the coal seam is realized,and the extraction time of the working face is shortened effectively. It is of great significance to mine pumping,digging,mining balance and safe production.
