山后矿区基于厚板理论的进路极限跨度设计研究OA

This paper mainly studies the stope design of deep metal mines.In the process of mining,the unreasonable design of route width will affect the mining efficiency and increase the filling pressure,so reasonable stope structure parameters are very important to ensure the safe and efficient production of the mine.For this reason,with the help of thick plate theory,this paper analyzes the roof tensile stress distribution,optimizes the design of several typical stope with depth from-282m to-500m in Shanhou mining area,and obtains the limit span value of each stope.The application of this study will provide reliable data for mine safety protection and engineering parameter optimization,and provide technical support for deep safe mining.
