摘要
小功率定向钻机在煤矿井下进行大直径高位定向钻孔需进行多次扩孔,施工时面临成本高、效率低、工艺复杂等问题,因此在施工中引入小功率定向钻机一次成孔工艺。基于此,介绍了大直径定向钻孔成孔工艺和钻具组合,为煤矿井下大直径高位定向钻孔施工提供了一种新方法,具有较高的推广应用价值。
Small power directional drilling rig needs to carry out multiple reaming for large diameter high position directional drilling in underground coal mine,which is faced with high cost,low efficiency,complex process and other problems during construction.Therefore,introduced the small power directional drilling rig one-time hole forming technology in construction.Based on this,introduced the large diameter directional drilling technology and drilling tool combination,which provides a new method for the construction of large diameter and high position directional drilling in coal mine,and has a high value of promotion and application.
