摘要: 针对金属矿地下开采引起的岩体移动问题,根据弹性力学理论建立了地表移动预测分析的三维理论模型,并用于鲁中铁矿地下开采引起的地表移动预测分析。在分析过程中,采用Matlab软件进行数值积分计算和图形绘制。通过工程实例计算分析表明,计算所获理论结果和实测数据基本一致。可见,所建立的数学模型满足工程精度要求,适用于研究分析金属矿体地下开采引起岩体移动变形以及地表建筑物安全评价。

Abstract: In light of the rockmass movement induced by the underground mining in metal mines, a three-dimensional theoretical model for forecasting and analyzing the ground surface movement is established based on the theory of elastic mechanics. It is used in forecasting the ground surface movement induced by the underground mining in Luzhong Iron Mine. In the analysis process, Matlab software is used in the numerical integration calculation and mapping. The calculation and analysis of the real engineering case show that the theoretical calculation results are basically in conformity to those practically measured. It can thus be seen that this mathematical model can satisfy the precision requirement of engineering and is suitable for studying the rockmass movement and displacement induced by the underground mining in metal mines and for assessing the safety of ground buildings.
