| 中文摘要: |
| 采煤影响后的岩溶地下水,强径流区的水动力特征虽未根本改变,但仍发生了明显的变化。采煤后,岩溶水的水流速率明显变慢,水力梯度加大,含水层间水力联系加强,因溶解矿物的差异也造成了水化学场的异同。因处于煤矿开发利用的不同阶段,不同径流区岩溶水水动力特征也存有明显的差异。 |
| 英文摘要: |
| This paper studies the impact of mining activities in coal mines on the hydrodynamic environment in runoff areas of karst water drawing from hydrochemistry and hydrogen oxygen isotopes. The conclusions showed that the hydrodynamic characteristics of a strong runoff karst water area had been significantly changed after mining activities. The water velocity became slow and the hydraulic gradient increased; hydraulic connections between karst groundwater and the others were compacted and complicated. The mineral dissolution and hydrodynamic environment varied with different disturbance intensities. The hydrodynamic environments of karst groundwater in various runoff karst groundwater areas were different with different developmental stages of coal mine. |
