摘要
本文介绍用浅眼留矿法回采湖北省大冶市刘家畈铁矿房柱法房间矿柱的实践 ,通过经验公式和三维有限元数值模拟对矿柱稳定性进行计算 ,结合工程实践经验确定了矿柱的回采工艺与尺寸 ,并对两种稳定性评价方法的适用性进行了评述。为最大限度回收矿产资源和提高矿柱回收率提供一定的理论依据 ,对类似矿山矿柱回收具有一定的借鉴作用。
This paper introduces the ribpillar stoping practice in the Liujiafang Iron Mine in Daye City,Hubei province using short-hole shrinkage system. It calculates the pillar stability by the empirical formula and 3-D Finite Element Method, confirms the craft and size of pillar stoping combining the engineering experience, and evaluates the characteristics of two methods and their applicability. It helps to the maximum recovery of mineral resources. It is useful for the similar pillar stoping in other mines.
