摘要 以曼家寨矿区东帮防渗治理为背景,通过对矿区边坡主要影响因素的分析,结合边坡岩性物理力学性质差、构造发育汇水面积大等现状特点,有针对地提出“网喷方式防渗治理试验”、“ (LDPE)土工膜边坡防渗治理试验”,并对试验结果进行优化,得出最大限度保留边坡岩体的原始强度,按设计坡形特性设计护坡,适应边坡的变形性,通过平台集中排水优化为斜分条辅助竖向集中排水为主边坡排水系统,才是降低边坡汇水渗透的关键,并通过水平疏干巷道的建设,改变了构造涌水对边坡涌水危害,快速疏干地表渗透水,降低了边坡地下水位线,提高了边坡稳定性,降低了边坡维护成本。

Abstract: According to the analysis of the main factors affecting the slope of the mining area, the paper combines the characteristics of the poor lithologic physical and mechanical properties of the slope and the large area of the structure development and water catchment area, and puts forward the "test on the control of seepage prevention by net spray" and the treatment of "(LDPE) geomembrane slope anti seepage control". According to the optimization of the test results, the improvement measures are put forward, and the original strength of the rock slope is preserved to the maximum. According to the design slope characteristics, the slope is designed to adapt to the deformation of the slope. Through the construction of horizontal and dry laneway, the damage of water gushing to the slope is changed, the seepage water of the ground surface is quickly drained, the water level line of the slope is reduced, the stability of the slope is improved and the maintenance cost of the slope is reduced.
