| 摘 要： | 高阳煤矿主采太原组9-10-11#煤层,矿区内断层、陷落柱发育,奥陶系灰岩溶裂隙水是威胁矿井安全开采的主要水源。据井下突水资料及地面水文地质勘探成果,总结出奥陶系峰峰组岩溶裂隙含水层的赋存特征:①从垂向上看,一段以泥灰岩、石膏、硬石膏为主,为相对隔水层,二段由青灰色及黑色厚层状泥晶、粉晶灰岩组成,钻探可见岩溶裂隙,富水性中等;②从水平方向上看,西部埋藏较浅区富水性明显强于中、东部深埋区,且在向斜轴部出现滞流区;③水位西高东低,相差近300m;④顶部存在隔水层段,隔水层厚度一般3.09~34.01m;⑤水位和水化学特征对比发现,峰峰组与马家沟组含水层没有水力联系;⑥地下水总体自西向东,自北向南径流,侧向径流排出井田外。该研究为煤矿底板水的防治提供了依据。

| Abstract: | The main mining coal seams in Gaoyang coalmine have Nos.9, 10 and 11 in Taiyuan Formation. Faults and subsided columns are well developed in the mine area; Ordovician limestone karst fissure water is main water source threatening safe mining. Based on underground water bursting data and surface hydrogeological exploration results have summed up Ordovician Fengfeng Formation karst fissure water aquifer occurrence characteristics. ① Vertically, the First Member is mainly relative aquifuge of marl, gypsum and anhydrite; Second Member is composed of cinerous and black thick-bedded micritic, powdered crystal limestone, drilling can intersect karst fissures; medium water yield property. ② Horizontally, water yield property in western shallowly buried area is obviously stronger than middle and eastern deeply buried areas; and stagnant area in syncline axial part. ③ Water level is high in the west, low in the east, about 300m difference. ④ Aquifuge sector exists in top part, generally 3.09-34.0hn thick. ⑤ After contrast of water levels and hydrochemical properties have found that there is no hydraulic connection between Fengfeng Formation aquifer and Majiagou Formation aquifer. ⑥ Totally, groundwater runoff is from west to east, north to south, lateral runoff is discharged outside the minefield. The study has provided basis for coalmine coal floor water control. |
