普朗铜矿自然崩落法采矿底部结构稳定性研究
|
摘要
本文通过对国内最大的自然崩落法采矿基地——普朗铜矿的进行地应力反演,并对矿体进行岩石力学特征评价,并对前期运营过程中底部结构的所受的应力状态进行了研究,以及对矿区采场中在拉底及出矿过程中,巷道的稳定性特征及破坏规律进行了对比分析,并且针对上述规律提出了普朗铜矿前期底部结构稳定性防护措施,对采矿实践有一定的指导作用。
Through the inversion of the in-situ stress of the Pulang copper mine, the largest natural caving mining base in China, the ore body is evaluated for its rock mechanics characteristics, and the stress state of the bottom structure during the previous operation is studied, and the mining area is the stability characteristics and failure rules of the roadway during the bottoming and mining process are compared and analyzed. The precautions of the bottom structure stability are proposed, which has certain guiding significance for mining practice.
