..., and optimized the excavation sequence of PBA construction method. Using numerical simulation and analytic hierarchy process, Wei Jing[12] et al. studied the optimal construction scheme of pilot tunnel in Huayuanqiao Station of Beijing Metro.Jia Shitao[13] used MIDAS/GTS NX software to simulate the construction...

... and in the vicinity of some important surface structures, is on the spot light. A stoping method and an extraction sequence are designed, using elasto-plastic numerical modelling to control surface subsidence, ensure operational safety and maximise ore recovery. The subsidence control measures adopted include leaving...

... holes are first drilled at the same intervals, and secondary holes are drilled diagonally between them. This halving sequence continues until the permeability of the sequence decreases sufficiently. These sequences are divided into two: one group of sequences is called the sequence of design holes where...
