樟村坪磷矿房柱采矿法采场稳定性研究

A study on the stability of the room-pillar mining method stope in zhang Cunping phosphate mine

用有限元法,块体理论及刚度法相结合,对樟村坪磷矿采场的稳定性进行了研究。研究结果表明:采场在结构面不太发育时是稳定的,结构面发育时则存在塌滑体;矿柱在其载荷超过强度时,仍具有一定承载能力。这与现场实际情况基本相符。

By means of the finite element method, block theory and stiffness analysis, the paper analyses stasility problem of the room-pillar stopes in Zhang Cunping phosphate mine. The results conform to the site states.
