摘要
为解案源煤矿Ⅳ-2煤层东部采区中房式残采区的富水性情况,针对Ⅳ-2煤层东部采区地质情况,采用瞬变电磁技术对该区进行了物理探测,IV-2煤层附近和煤层顶板上方25 m砂岩含水层处分别有1处和3处相对富水区,其余区域均为弱富水区。该探测结果为下一步回收房柱过程中的防治水工作提供了较为可信的参考依据。
To understand the water-rich situation of Zhongfang residual mining area in the eastern mining area of the IV-2 coal seam in the source coal mine,the physical exploration of the area was carried out by transient electromagnetic technology according to the geological conditions of the eastern mining area of the IV-2 coal seam.There are 1 and 3 relatively rich water areas near IV-2 coal seam and 25 m sandstone aquifer above coal seam roof,and the rest are weak water rich areas.The results provide a reliable reference for the prevention and control of water in the next recovery process.
