摘要
通过对湘西上洞街煤矿区毛家寨段水文地质测绘、地质钻探及邻近生产矿井资料收集,综合分析研究认为:勘查区煤矿床主要充水主要为其顶、底板岩溶裂隙水,目前岩土工程地质条件比较简单,环境地质现状良好。煤矿开采后,因大量疏排岩溶地下水而导致的水、工、环不良地质问题将是今后矿区防治工作的重点。
Through hydrogeological mapping, geological drilling in Maojiazhai sect of Shangdongjie coalmine and data collection from adjacent operating coalmines,after comprehensive analysis,the author figured out that the main water filling source is karstic fissure water from coal seam roof and floor. At present, the geotechnical engineering geological condition is rather simple, and the environmental geological status quo is in condition. But after the mining operation is started, the harmful hydrogeological, engineering and environmental geological problems caused by large quantity karstic underground water drainage will be the focal point of the mine＇s hazard control.
