全液压车装钻机在集束式潜孔锤反井施工中的应用

Application of All Hydraulic Truck-mounted Drilling Rig in Cluster DTH Inverse Well Construction

摘要:

采用SDC1500型全液压钻机配套新型集束式反井气动锤施工工艺，成功解决了传统的反井钻机效率低下的问题。结合内蒙古自治区准格尔煤田黄玉川煤矿大直径排水井工程，对该施工工艺方法进行了总结。

Abstract:

Almost all the drilling contractors accomplish inverse well construction with mechanical raise boring machine, but it usually works inefficiently. Engineers in CNIET have developed a fast and safe process to drill inverse wells by adopting SDC1500 all hydraulic truck-mounted rig matched with new cluster inverse well pneumatic DTH to solve the inefficiency. This construction process is summed up with the case of large diameter drainage well in a coal mine of Inner Mongolia.
