斜孔升降工序机械化是今年技术革新项目重点之一。根据省局与队党委的指示，经在12号和32号钻孔进行四十一天生产试验证明，使用效果良好。试验中使用XB-500型钻机，75°斜孔16米高斜塔、孔深401米，28个立根，上下钻具722次、上下立根12345次。试验情况介绍如下： The mechanization of the inclined hole lifting process is one of the focuses of this year’s technological innovation project. According to the instructions of the provincial bureau and the party’s party committee, it was proved that the use effect was good after forty-one production trials were conducted on drill holes 12 and 32. The XB-500 drilling rig was used in the test, with a 16-meter high inclined tower with a 75° inclined hole, a hole depth of 401 meters, and 28 stand-ups with 722 drills on the upper and lower sides and 12345 on the upper and lower stands. The test situation is described as follows:
