摘要
针对陈四楼煤矿六采区DF18-1正断层发育情况及导水性是否影响采掘接替问题,结合三维地震勘探资料,采用井下钻探的方法,对DF18-1正断层的发育情况及导水性进行探测,根据探测结果确定断层三要素及导水性,从而制定采掘计划。该方案工程量小,施工组织方便,探测结果准确。
In view of the development of DF18-1 normal fault and whether the water conductivity affects the mining replacement in the sixth mining area of Chensilou Coal Mine,combined with the three-dimensional seismic exploration data,the development and water conductivity of DF18-1 normal fault are detected by underground drilling,and the three elements and water conductivity of the fault are determined according to the detection results,so as to formulate the mining plan.The scheme has the advantages of small quantities,convenient construction organization and accurate detection results.
