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。
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.
