Underground mines account for 40 percent of global mining operations across numerous commodities and deposit types and employ a variety of mining methods across a broad geographical distribution, and with a wide range of labor productivity and costs This inherent variability means that each individual mine faces a specific set of operating conditiIn this paper, we propose a method to combine them to monitor surface subsidence deformation in mining areas This approach complements the advantages of the two technologies to Surface Subsidence Monitoring Induced by
Once a decision has been made to go underground, the specific mining method selected depends on the size, shape, and orientation of the ore body, the grade of mineralization, the strength of the rock materials, and The mining method selection for underground mining is one of the most important decisions when designing a mine This selection depends on the mininggeological, miningtechnical and economic factors(PDF) Application of UBC methodology for underground
