| 摘 要： | 晋城矿区王台铺煤矿经过多年的开采，上煤组（3#煤）资源枯竭，目前开采下组煤（9#煤和15#煤），面临着上组煤采空区积水的威胁。运用地质资料和瞬变电磁法对该矿九五盘区上部采空区积水进行了预测。井下的泄水孔排水量证实，运用地质分析法预测的水量偏大，瞬变电磁法的水量偏小，但总体误差不大。本次泄水的成功，可解放9＊煤层145万t的可采储量，确保矿井采掘衔接的正常，同时也可从根本上杜绝了矿井突水事故的发生。

| Abstract: | After years of mining, the resources of upper coal group （coal seam No.3） have been exhausted in the Wangtaipu coalmine, Jincheng mining area. Currently mining lower coal group （coal seams Nos.9 and 15） are confronted with threat from upper coal group gob area ponded water. Using geological data and transient electromagnetic methods carried out prediction of ponded water in area above gob of the fifth panel of No.9 coal. The discharge of underground drainage opening has been confirmed that the predicted amount of water from geological analysis is on the high side, while from transient electromagnetic method on the low side, but not large in overall error. The successful water drainage can unbind 1.45 million tons of No.9 coal seam mineable reserves. That can ensure proper link up of mine winnings and openings and put an end to happen of water bursting. |
