赵家寨矿井二_1煤层开采矿井充水特征分析

Analysis on Water Filling Characteristic in Ⅱ1 Seam Mining of Zhaojiazhai Coal Mine

在分析赵家寨矿井水文地质条件及存在的主要水害问题的基础上,着重从矿井涌水量和地下水位监测孔水位变化两方面对矿井充水特征进行了分析,得出造成该井田底板水害的主要原因是垂向导水构造,以及二1煤层直接底板充水含水层与深部灰岩含水层之间垂向水力联系。提出了今后水害防治工作的重点。

On the base of analysis of hydrogeology conditions and main existing water hazards problems, mine water filling characteristics are studied on water yield of mine and groundwater level of monitoring wells,it can be concluded that key factor of floor water hazards is vertical water transmitting structure and there are closely vertical hydraulic connection between floor aquifer and deeper limestone aquifers. Finally, later working emphasis of prevention and measure of water hazards is put forward.
