摘要
针对三道庄矿采矿方式,分别用有限元数值模拟和简化梁法等方法计算得出了不同采空区跨度所要求的安全隔层厚度,综合确定了河南栾川三道庄钼矿露天与地下联合开采的合理隔层厚度。
In view of the combined open - pit and underground mining in Sandaozhuang molybdenum mine, Henan province, the needed thicknesses of safe partition pillar for the different spans of goal were calculated out respectively using finite element simulation and beam theory of structural mechanics, and the reasonable thickness of safe partition pillar for the combined open - pit and underground mining in this mine was determined also.
