摘要
房柱法开采缓倾斜互层矿体时形成复杂的岩体工程,其采场结构参数严重影响着采矿作业的安全性和经济性。本文针对缓倾斜互层矿体提出了矿房合理布置形式,并通过多种理论计算与分析确定了采场结构参数,为应用房柱法开采类似技术条件的矿体提供了完整的研究路线和快速的解决方案。
According to the specific characteristics of the complicated slightly inclined multi-layer phosphate ore bodies and the present production status,the mining method for one troublesome phosphate ore-body was studied in this paper.On the basis of the comparison of several suitable mining methods for this kind of ore-body,the paper recommends the efficient multi-layer tunneling room and pillar mining method with pre-control roof and mechanization,which can provide references for other ore-body with the similar mining technical conditions.
