复杂地质条件矿井水平定向钻进施工技术分析
An Analysis of the Horizontal Drilling Technology in Coal Shafts with Complicated Geological Conditions
摘要
我国引进的煤层水平定向钻进技术,应用于煤矿井下地质构造探测和高瓦斯矿井抽采瓦斯收到了良好的效果,但在地质构造复杂的矿井,水平深孔钻进受到诸多因素的制约。文章结合焦家寨煤矿工程实际,分析探讨钻进施工技术,对地质条件相似的煤矿进行水平定向钻进具有借鉴作用。
Abstract
The introduced horizontal drilling technology may well apply to geological structure detection,and for gas discharge.However,in shafts where the geological condition is complicated,this technology is restricted by many factors.This article,by taking the e
