Abstract:
      Stope support has always been one of the technical problems to be solved in the mining of weak and broken deposits. Based on the rock mass quality classification results, an optimization plan was proposed to solve the technical difficulties faced in the process of stope support in weak and broken ore body. Then, a stope for field application was selected. In the field application, the scheme lead to a significant increase in mining efficiency, has been proved to be economical and able to control deformation and displacement, which is suitable for large-scale promotion in the mining of the same type of ore body.
