摘要
分析了矿区的工程地质情况,并提出相应的采矿方法;依据矿体上下盘围岩的力学性质、工程技术条件和采矿方法,设计了3种地下开采方案,并对比了其优缺点和综合技术经济指标,最终确定出最优方案,为类似工程提供参考。
The geological status of mining area is analyzed. According to mechanical properties of upper ＆ lower plate＇s wallrock, engineering--technological conditions and mining methods, three alternatives for turning the open pit mine into underground mine are established. Based on comparison of their advantages ＆ disadvantages and techno--economic indexes, the optimum one of the alternatives is selected. The experiences in the case is referential for similar projects.
