| Abstract: | The stratum is complicated in Dabaoshan molybdenum mine. Leakage, block falling, borehole collapsing and di-ameter shrinkage often occurred and coring was difficult for drilling tool breaking, sticking, bit burning and burying. By se-lection of rational drilling technologies, wall protection and leakage control methods and drilling coring methods, the de-tailed survey and prospecting drilling were smoothly completed. The paper introduced the drilling technology in the complex formation of Dabaoshan molybdenum mine. |
