河南平禹煤电有限公司一矿处在禹州岩溶水系统最下游的承压自流排泄区，煤层底板太灰和寒灰岩溶发育，富水性和导水性强，补给充沛，易发生突水事故。矿井属于水文地质极复杂类型的煤矿。地下水可分为基岩裂隙水、碳酸盐岩类岩溶水、碎屑岩类孔隙裂隙水和松散岩类孔隙水四个类型。根据矿区地质和水文地质特征，提出了区域治理和局部治理相结合、浅部帷幕注浆截流、井田疏水降压和局部底板注浆加固相结合、井下物探与钻探相结合、堵水和排水相结合的综合防治水方案。

No.1 Mine of He'nan Pingyu Coal Power Co., Ltd. is located in the pressure-bearing artesian drainage area in the lowest reaches of the karst water system in Yuzhou, so limestone water in Taiyuan formation and Cambrian limestone water devel-op at the coal seam floor, with strong water yield property and water transmissibility as well as abundant supply, leading to fre-quent water inrush. Mines belong to coal mines with extremely complicated hydrogeological types. The groundwater can be di-vided into such four types as bedrock fissure water, karst water in carbonate rock, clastic rock fracture pore water and pore water in loose rock. According to the geological and hydrogeological char-acteristics of mines, we proposed the following comprehensive water prevention and control program, including combination of regional control and local control,shallow curtain grouting closure, combination of hydrophobic depressurization and partial floor grouting consolidation,combination of geophysical prospecting and drilling prospecting, combination of water shutoff and drainage.
