应用综合勘查方法分析平朔安太堡三号井工矿突水原因

平朔公司安太堡三号井工矿2007年3月在首采工作面辅运顺槽掘进时，迎头冒顶突水，初期突水量达6000～8000m^3/d，将1289．16m标高以下淹没。在分析研究区地层、构造及水文地质条件的基础上，对沙沟河道进行了渗漏观测，对地表排污水、沟水和井下突水点的水质进行了分析化验，有针对性的布置了6条物探线，最后进行了钻孔验证，综合分析认为突水水源主要为大沙沟河道的侧向补给，突水通道为NW向的强风化带。提出了加大井下排水，地表对大沙沟河进行土工膜防渗处理的综合治理措施。

Pingshuo Antaibu No.3 Underground Coalmine Water Bursting Causation Analysis through Integrated Exploration

During the Pingshuo Coal Company Antaibu No.3 underground coalmine first stage winning district working face auxiliary haulage crossheading advancing in March 2007, a head-on roof fall and water bursting happened, initial stage water bursting inflow was 6000-8000m^3/d, under 1289.16m level inundated. Based on research area analysis of stratigraphy, structure and hydrogeological condition, carried out Dashagou River channel leakage observation, analyzed and tested water quality of surface sewage, ditch water and water from underground bursting, 6 geophysical prospecting lines laid out purposely and validated by drilling finally. After integrated analyses, considered that water bursting source is mainly from lateral recharging of Dashagou River, water bursting channel is NW direction strong weathering zone. Comprehensive harness measures to increase underground drainage, Dashagou River geomembrane impervious processing etc. put forward.
