【摘要】 根据西石门铁矿马河下矿床开采的具体工程实例,采用拉格朗日元法对“对采”和“背采”2套方案的全过程进行数值模拟。通过对计算结果中的采区渗水量、河床水平应变和垂直位移的对比分析,表明:马河下矿床的开采是可行的,并且背采方案更为科学合理。更多还原

【Abstract】 Taking the project of mining the iron ore deposit under the Ma River bed in Xishimen Mine as the study case, a numerical simulation was made of the whole process of two mining schemes, namely "face fo face extraction" and " back to back extraction" by Lagrangian method. The comparison and analysis of the amount of water infiltrating into the mining areas and the horizontal strain and vertical displacement of the river bed in the calculation results indicates that it is feasible to exploit the deposit under Ma River bed and the "back to back mining" scheme is more scientifically reasonable.更多还原
