放矿中黄土覆盖层运动规律的数值模拟

Numerical Simulation on Movement Law of Upper Loess Covering During Ore Drawing

针对大冶铁矿铁门坎东采区的回采现状 ,运用放矿椭球体理论和计算机数值模拟技术 ,对矿体顶部黄土层在放矿中的运动情况进行了多方案的全历程模拟 ,并与物理模型试验对比 ,两者从过程到结果 ,从图形到数据都很一致 ,反应了采用数值模拟方法进行土。

In light of the present status of extraction in Tiemenkan east section of Daye Iron Mine and using ellipsodial theory of ore drawing and computer numerical simulation technique, multischeme simulation of the whole process of the movement of upper loess covering was made and compared with physical model experiment. Good agreement was found between the two, from process to result and from graph to data, showing that it is feasible to adopt numerical simulation to study soil and rock ore drawing.
