摘要
地下采场底部结构是地下矿山采场开采设计的重要部分,对底部结构的设计需考虑的因素包括矿床的工程地质条件、矿体产状、矿岩稳固性、资源储量和品位、采矿方法、铲装运输设备、开拓系统等,其目的是确保安全生产,提高生产效率,降低贫化损失。
The bottom structure of underground stope is an important part of the mining design of underground mine.The factors to be considered in the design of the bottom structure include the engineering geological conditions of the deposit,the occurrence of ore body,the stability of ore and rock,the reserves and grade of resources,mining methods,shovel loading and transportation equipment,development system,etc.The purpose is to ensure safe production,improve production efficiency and reduce the loss of dilution.
