摘要
根据眼前山铁矿矿体赋存条件以及开采现状,分析了该铁矿露天转地下开采过程中挂帮矿体开采、采空区处理、覆盖层形成、开拓系统以及开拓系统在时间、空间、产量衔接等技术方面的问题。
The conditions of ore occurrence of Yanqianshan Iron Ore Mine and the recent mining state are explained. On this basis, the problems related to change from open pit mining to underground mining such as mining of pit wall ore, treatment of exhausted area, forming of overburden layer, link up of development systems （in respects of time, space and output qty） are explained.
