摘要
The formation is typical complicated in Chenghe mining area of Weibei, drilling construction is difficult with low drilling efficiency. By the analysis on the difficulties in drilling process, the drilling technical experience was summed up. According to the drilling in thick loess layer, borehole leakage and collapsing, hard rock and pulverized coal taking, the relevant technical measures and drilling technologies were put forward.
