Improvement of upward horizontal slicing and filling mining method in Huogeqi Copper Mine

The upward horizontal slicing and filling mining method is successfully used in Huogeqi Copper Mine.Through two years mining practice,it is found that some ore body in the Huogeqi Copper Mine middle CuI ore body are broken.If the original filling mining method is continued to be used,it's difficult to meet the requirement of normal production.In view of this,the quarry structure parameters are adjusted and perfected.By analysis and comparison of various technical and economic indicators,it's found that using the adjusted quarry structure parameters of upward horizontal slicing and filling mining method are optimized,which can be reference for other mines.
