铜山铜矿采场顶板安全厚度分析计算及应用

摘要

在对铜山铜矿矿岩工程地质调查研究及岩石力学参数试验的基础上，分别采用传统的采空区顶板安全厚度分析法、极限分析法和弹性力学小变形薄板理论分析法计算了采空区顶板的安全临界厚度。计算结果很好地指导了采矿现场工程实践，为铜山铜矿安全生产、减小采矿损失贫化发挥了作用。%Based on the study of engineering geological survey on ore rocks in Tongshan Copper Mine and tests on rock mechanical parameters ,the paper respectively applied traditional analysis of safety roof thickness in mined -out ar-ea ,limit analysis method and small deformation plate theory analysis of elastic mechanics to calculate the critical safety roof thickness in mined-out area.The calculation results well guided field works in mines ,contributing to safety pro-duction in Tongshan Copper Mine ,minimizing loss and dilution rate .
