眼前山铁矿转井下深部开采影响安全生产主要技术问题的可行性分析

Analysis of Feasibility of Main Technical Issues of Impact of Transition from Open Pit to Deep Underground Mining of Yanqianshan Iron Ore Mine on Safety Production

论述了露天转入井下深部开采主要技术方案的可行性;分析了井下深部开采的合理开采顺序、产量衔接、井下通风系统、采矿方法选择、周边环境条件影响及对露天坑采取的安全措施等问题,实践表明,该技术方案可行。

This paper demonstrates the feasibility of the main technical plan forr transition from open pit to underground deep mining and analyzes the issues of reasonable mining sequence, output connection, underground ventilation system~ mining method selection; influence of ambient conditions and safety measures taken for the open pit. The practice has indicated that the technical plan is feasible.
