Numerical Optimization of Hidden Edge Stope Mining in Underground Metal Mines

[摘要] In a metal mine, there was a great risk of mining hidden resources due to unreasonable mining in the early stage. In order to effectively and safely mine this part of the resources, with the displacement as the objective function, a preliminary optimal dynamic programming model for the mining sequence of the unstable collapse zone was established and determined the preliminary plan. Using numerical analysis methods to optimize the mining sequence of the stope in the unstable collapse area. The results show that: 1) From the dynamic programming model, four feasible preliminary schemes are determined from the 10 schemes of possible mining sequence according to the numerical analysis results; 2) Mining from the S1-2# stope is the most reasonable. After comprehensive judgment, the optimal mining order of hidden danger stope is from S1- 2# to N1-2# and then S1-1#.The next order is from N0-1# to S0-1# and 0#.The research's results could provide reference for safe mining of similar mines.
