崩落法和充填法联合开采在金山店铁矿的应用研究

Application Study of Caving Method and Filling Method Combined Mining in Jinshandian Iron Mine

随着国家对土地资源和环境保护的日益重视以及征地搬迁费用的增加,同区段崩落法和充填法联合开采得到越来越多的金属矿山企业的青睐。以金山店铁矿为例,采用理论分析、数值模拟等方法对该开采方法可行性进行了验证,并给出了采场优化布置方式和地表控制效果分析,以及2种开采方法之间衔接层的安全厚度。

With the state increasing attention to land resources and environmental protection and increase of reloca- tion expenses, the caving method and filling method combined mining at the same block becomes more and more popular a- mong mental mine enterprises. Taking Jinshandian Iron Mine as example, the feasibility of the combined method is studied with theoretical analysis and numerical simulation, displaying the optimized stope layout and the effect of ground control, de- termining the safety thickness of link layer between two kinds of mining methods.
