Brief Introduction of the Testing Process

At the beginning, the performance of the   entering rock increased by 18% compared with the early product. When it drills   to 1100m, the drilling time keeps increasing; At that time, the clients   requires to bring drill bit out. The failure of the bit bearing is rejected   according to the experience-based judgement analysis (when HDD Reamer comes   to the same layer, the drilling time increases slightly), so it can be   determined that the drilling work can be continued for the observation. When   it drills to 1310m, the drilling time decreases a bit and comes back to   normal. The excavating work goes smoothly.
