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。
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 example of Jiajiazhai Coal Mine,tires to analyze the drilling technology,which provides a good reference for coal mines with similar geological conditions.
