基于定向水平钻进技术的构造精准探查

Precise exploration of structures based on directional horizontal drilling technology

辛安矿地质构造极为发育,水文地质条件复杂,尤其在矿井-500北翼地区,在2010年和2011年采掘活动中,发生2次奥灰突水事故,造成淹井停产。在构造未查明的情况下进行采掘活动极易发生水害事故,同时,辛安矿存在水文地质条件复杂、涌水量大、水压高等特点,井下探查构造存在很大的安全隐患。经研究论证采用地面水平定向钻进技术对区内构造情况进行精准探查。

Xin'an mine has extremely developed geological structures and complex hydrogeological conditions,especially in the area of the-500 north flank of the mine,where two ash water emergencies occurred during the mining activities in 2010 and 2011,resulting in the suspension of production by flooding.The mine is prone to water damage accidents when the structure is not identified.At the same time,Xin'an mine was characterized by complex hydrogeological conditions,high water gush and high water pressure,and there were great safety hazards in exploring the structure underground.It was proved that the horizontal directional drilling technology was used to accurately investigate the structural conditions in the area.
