【摘要】 针对晶鑫煤矿二盘区3203工作面水文地质条件复杂、地质构造带涌水量异常增大等问题,提出了超前探水与三维地震勘测相结合的综合探测技术体系,探明了盘区内矿井水分布及涌水量大小,解释了构造带涌水量增大的原因是顶板砂岩水沿采动裂隙涌出,降低了钻探工程量,同时增加了钻探结果的可靠性与准确性。更多还原

【Abstract】 In view of the complex hydrogeological conditions and the abnormal increase of water inflow in tectonic belt in 3203 working face of No.2 panel in Jingxin coal mine,the paper puts forward an integrated detection technology system combining the advanced water-detection and 3D seismic survey technology.It ascertains the mine water distribution in panel and the water inflow;explains the reason water inflow increase in tectonic belt is for the roof sandstone water gushing along mined crack;reduces the drilling work amount and increases the reliability and accuracy of drilling results.更多还原
