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.

Key words: Net spray method for seepage, Geomembrane slope seepage, Control treatment test, Slant strip drainage, Vertical concentrated drainage, Drainage roadway.
