Technical test and results of “shotcrete floating platform” for slope treatment at the open pit mine

Abstract:

There are some safety risks such as exposure of the mountain, vegetation damage, soil erosion, rolling dust, geological hazards due to the irregular exploitation of mineral resources and quarries. The state and local governments at all levels attach great importance to the ecological restoration for mines. In the ecological recovery and management for mines, traditional treatment for high and steep slopes from mining is mainly slope grading; that is, the slope is trimmed from the top to the bottom, and then the platform and the slope are greened. However, with this method, there is some construction difficulty, and a large amount of work due irregular mining operations; meanwhile, it will further damage the ecological environment, and it takes a longer time to cover the slope with green plants. In view of these circumstances, a new type of technology called “shotcrete floating platform for the restoration of the mining environment” (in short “shotcrete floating platform”) was innovatively developed. Field experiments demonstrated that it solved the technical difficulty in high steep slope treatment for ecological recovery at the mines and quarries, and reduced additional destruction of the ecological environment with simple and rapid construction, and quick effect; at the same time it provided effective control of geological hazards.
