The occurrence is steep with ore concentrating in Chengjiagou-Shagou silver polymetallic ore deposit.Because drilling designs are mostly branch holes with medium depth and large slope, the borehole quality is the key technology.By the construction case of 1550m inclined hole, the paper introduces the selection of medium-depth inclined hole drilling technology and the concrete measures for ensuring drilling hole curvature.
