(Dept. of Min. Eng. University of Science and Technology Beijing; Beijing 100083; China)
Abstract: This paper. combining microcomputerized FEM modelling with orthogonal test design thatis a widely used mathematical statisties method , presents the optimization of the panel mining sequence of the Xishimen Iron Mine in Northern China at the obJective of rock mechanics. The results shows that the mining sequence between the panels has a great influence on the stability ofthe draw openings on near footwall ,and the optimum mining sequence may be advancing in thebenched working line which is oblique to the strike of the orebody.
