【Abstract】 Estimating the stability of stope is a complicated problem. In this paper, the extension method for evaluating the stability of the stope roof is introduced; a stope stability evaluation model with muliti-indexes parameters is established. The evaluation results are shown by quantative figure which can fully reflect the comprehesive stability of actual stope.更多还原
