利用EH-4电磁成像系统对砟子煤矿工业广场保护煤柱进行了探测,以确定保留煤柱南部边界线附近是否存在采空区.探测以一条长线与二条垂直短线展开,长线查证煤柱南部边界采空区的范影响围(长度),短线查明采空区的纵向深度(宽度).根据长测线各线段及短测线电阻率剖面图,结合预留煤柱范围内煤层底板等高线,确定在保护煤柱南部边界线附近,存在一个长520m,宽95m,平均高度105m的异常区.参考该区地质勘探资料,异常区的深度与煤层赋存深度一致,据此解释为采空区.为保障矿区安全生产,建议禁止回采工业广场南部异常区.

Using EH-4 electromagnetic imaging system detected coalmine ground installation area protective coal pillar of the Zhazi coalmine to find out if the worked-out area existed near the retained pillar southern border. The detection has laid out one longer line and two orthogonal shorter lines, the longer line to check out pillar southern border worked-out area incidence (length), the shorter lines to check out worked-out area longitudinal depth (width). Based on longer line each sector and shorter line resistivity sections, combined with retained pillar coal floor contour have determined that near the southern border, an abnormal region with 520m long, 95m wide and average height 105m existed. Referred to geological exploration data in the area, the depth of abnormal region is consis-tent with coal seams hosting depth, thus interpreted as worked-out area. To ensure mine area safe production, coal winning within southern abnormal region should be prohibited.
