莲盛煤矿地下开采对地下水资源影响的预测与分区研究

Prediction and Zoning Study on the Impact of Underground Mining on Groundwater Resources in Liansheng Mine

合理预测煤矿开采对地下水资源的影响,对区域地质生态环境保护和矿区规划具有重要意义,以莲盛煤矿为例,建立了评价目标含水层潜在地下水资源量的变权模型;对传统经验方程进行改进,预测导水裂隙带高度;提出了开采对地下水资源影响的分区标准;利用水文地质试验数据和钻孔摄像系统分别对地下水资源量和导水裂隙带高度预测结果进行了验证,并根据分区结果提出了水资源保护措施。

Reasonable prediction of the impact of coal mining on groundwater resources is of great significance to regional geo-ecological environmental protection and mine planning.Taking Liansheng coal mine as an example,a variable weighting model was established to evaluate the potential groundwater resources in the target aquifer.The study improved the traditional empirical equations to predict the height of the water-conducting fracture zone and proposed zoning criteria for the impact of mining on groundwater resources.Through the hydrogeological test data and borehole camera system,we verified the prediction results of groundwater resources and water-conducting fracture zone height respectively,and proposed water resource protection measures based on the zoning results.
