定向钻机在探放水方面的技术应用

Technical application of Directional Drilling Machine in Water Detection and Release

青洼矿22061巷西北部临近原青洼煤业一采区采空区,由于开采时间较为久远,水文地质资料不足,采空区边界不清楚,采空区积水严重威胁2206综放工作面的安全采掘。为探清采空区范围,保证巷道掘进安全,采用ZDY6000LD全液压定向钻机对采空区范围进行探测,圆满完成了探测采空区边界的任务。

Aiming at the threat of serious goaf water to the safe mining at 22061 fully-mechanized caving face in Qingwa Colliery due to the long mining time,the lack of hydrogeological data,the unclear goaf boundary,the paper introduces the application of ZDY6000LD fully-hydraulic directional drilling machine to explore the scope of the goaf and ensure the safety of roadway excavation,which can successfully complete the task of detecting the goaf boundary.
