| 摘 要： | 为进一步查明南屯煤矿奥陶系石灰岩含水层的水文地质条件,正确评价奥陶系石灰岩含水层对下组煤开采的影响,本次研究利用井下现有的水文地质观测孔,对奥陶系石灰岩含水层进行了群孔放水试验,进行三个落程的放水,并应用GMS软件进行数值模拟分析,计算水文地质参数,预计奥陶系石灰岩疏水量。该结果表明,奥陶系石灰岩含水层放水基本上对十四灰含水层没有产生较大的影响,对奥陶系石灰岩水尽量采用避让措施,通过物探等手段寻找导水通道,并及时对其进行处理。

| Abstract: | Dewatering tests of the Ordovician limestone aquifer were conducted in order to further examine the hydrogeological conditions and evaluate the influences of Ordovician limestone aquifer for mining of lower group of coal seams in the Nantun Coal Mine. The existing hydrogeologcal observation holes are used to carry out the dewatering tests. Three falls in groundwater levels were performed in the tests. Simulation analysis was carried out by using the software of the GMS,which can be used to identify the hydr... |
