Study on grouting reinforcement test of north slope surface fracture zone in Fushun West Open-pit Mine
In order to study the subsidence deformation disaster prevention and mitigation in Fushun urban ground crack development area, we select different deformation sections of surface fault zone in Fushun West open-pit mine to carry out grouting reinforcement tests with sleeve valve tube method and full hole grouting method. Through the field practice, the rock mass is seriously broken and cavitated in the depth range of 18.50-25.5 m in the test area. F1A fault zone with full hole grouting method is better than sleeve valve tube method. It is better to use sleeve valve tube method in F41 fracture zone. Through the comparison of permeability and permeability coefficient before and after grouting, as well as drilling coring, it is shown that grouting reinforcement plays a filling and consolidation role in the test area, which is suitable for the treatment of deformation and failure of ground cracks.
