气动潜孔锤在七台河国有煤矿深部采空区的应用

DTH+Diamond Rope Core Drilling Process of State-owned Coal Mine in Qitaihe Deep Application Gob

针对黑龙江省七台河国有矿山西部区深部煤炭资源勘查项目工作实际,详细说明了钻进中所采用的"采空区层段使用气动潜孔锤"技术的应用,极大地提高了钻进生产效率,实现在钻过多层采空区下寻找煤炭资源的技术攻关,并实现了找煤成果突破。

In this article,the state-owned mine in Heilongjiang province,the western Qitaihe the deep coal resources exploration project actual details used in the drilling,＂gob layers using DTH＂＋＂non-use of mined-diamond rope layers Core ＂construction technology and methods of drilling,the technology has greatly improved drilling efficiency and achieve in the next drilled multiplayer technology research looking for coal resources,and achieve breakthrough results searching for coal.
