摘　　要：在分析高庄煤矿第四系煤层顶板基岩地质、水文地质特征的基础上,开展水上地质雷达和水上并行高密度电法探测研究,并对湖底地形开展水上地质雷达探测,查明历史采砂情况,对湖底第四系含水层开展水上高密度电法探测,查明历史采砂对第四系中部黏土隔水层的破坏情况。综合两种探测手段,明确了微山湖上非法采砂对矿井第四系底部含水层的影响情况,划定了第四系底部含水层和第四系上部含水层沟通的区域,为采砂扰动条件下湖下安全开采提供了安全保障。In this paper,on the analysis of the geological and hydrogeological characteristics of the roof bedrock of quaternary coal seam in Gaozhuang Mine,a study on Ground Penetrating Radar(GPR) and parallel high-density electrical detection in water was conducted.The GPR survey was carried out on the topography of lakebed to identify the historical sand mining;the high-density electrical survey was carried out on quaternary aquifer of lakebed to identify the damage caused by historical sand mining on the quaternary clay barrier.The combination of the two methods clarified the impact of illegal sand mining on the bottom of the quaternary aquifer at Weishan Lake.Accordingly,the area where the bottom aquifer and the upper aquifer of the quaternary communicate was delineated,providing a guarantee for the safe mining under the sand mining disturbance.
