Wire-line coring hydraulic hammer was mainly adopted to prevent hole deviation in the deep hole exploration of Xinyumeishan coal mine. The drilling tool structure combination was optimized and drilling technical parameters and the measures were rationally selected, deviation control effect was obvious. The paper summed up the experience of deviation prevention with SYZX wire-ling coring hydraulic hammer in the deep hole exploration construction of Xinyumeishan coal mine in Jiangxi.
