清平磷矿地处四川省绵竹县清平乡境内,始建于1964年,是一具有发展前景的大型矿山。燕子崔矿段位于矿区中部,长达3300m,系清平磷矿主要开采地段。该矿以井下开采为主,为确保井下生产的安全,提高资源利用率,笔者在评述主要岩层的岩石力学性质的基础上,结合大量工程地质调查资料,采用赤平极射-实体比例投影的方法,图解出各岩层块裂结构体的破坏可能形式和规模,并采用块体平衡理论计算方法评价其稳定性。
Qingping Phosphate Mine is located in Qingping Township, Mianzhu County, Sichuan Province, was built in 1964, is a large-scale development prospects of the mine. Swallow Cui ore section is located in the central mining area, up to 3300m, Department of Qingping phosphate mining area. In order to ensure the safety of underground production and improve the utilization of resources, the author, based on the review of the rock mechanics properties of the main rock formations, combined with a large amount of engineering geological survey data and the method of stereographic projection-solid ratio projection , The possible forms and the scale of destruction of the rock mass fault structures are illustrated, and the stability of the block equilibrium theory calculation method is evaluated.
