| Abstract_FL | The Xiadian gold mine has already experienced the deep mining, the stope by the caving method and filling method is affected by multiple disturbance stress. It is very important to determine the reasonable stope size and the stability of surrounding rock for the safety operation of the mine. The parameters of discontinuities around the experimental stope were obtained by using the advanced photogrammetry technique, and the stability of surrounding rock mass of the experimental stope was evaluated by multi-method. On the basis of this, the parameters of the stope are optimized by using the Mathews method and the span experience formula. Finally, through the numerical simulation, the rationality of the obtained experimental stope size is analyzed and verified. The successful application of the optimized stope size in the mine designed by Mathews method,verified the feasibility of the graphic method in the design of the stope size under complex stress. |
