SHI Zhijun;LIU Jianlin;LI Quanxin;CCTEG Xi'an Research Institute;  
Based on representative achievements of both surface and underground drilling technique and equipment since"11 th Five-Year Plan",new pattern of high-efficiency "spatial-temporal integration"development of coalbed methane( gas) in coal mining area is summarized. Then the latest development of both surface and underground drilling technique and equipment is introduced,followed by analysis of characteristics and application prospects of the matching drilling technique and equipment for ground remote butted wells,and underground directional borehole with large diameter and length,combined with field applications,Finally,in light of the production demand in coal mining area,the problem faced with underground drilling in coal mine is further analyzed,and corresponding development direction is put forward which is expected to provide a reference on the application of drilling technique and equipment in coal mining area.
