Different secondary stress field would be formed with different mining process and filling sequence. By means of reasonable arrangement and adjustment of the mining sequence of orebody, the stress distribution of the surrounding rock is able to be remarkably changed, the current excavated working face is able to be in the stress-reduced area and the phenomenon of stress concentration in course of mining process could be also avoided. Rational mining sequence is able to largely improve the stability of stope and the security of working face. According to multilayer orebody occurrence characteristics and mining technical conditions of Laochang 13-8^# ore groups, by using 3Dmine-MIDAS/GTS-FLAC^3D coupled numerical simulation method, numerical simulation study on the mining sequence of multilayer orebody is carried out and four kinds of optimization schemes of multilayer orebody mining sequence are put forward, namely, downward mining from upper to lower, overhead mining from upper to lower, downward mining from lower to upper, and overhead mining from lower to upper. By applying the multi-index comprehensive evaluating model based on index contentment degree and considering stress fields, displacement fields, and crack fields comprehensively, the four multi-index comprehensive contentment degrees of the optimization schemes for mining sequence are 0.684, 0.641, 0.653, and 0.683, respectively. The contentment degree of the overhead mining from lower to upper is 0.683. Therefore, the result indicates that the overhead mining from lower to upper is feasible in the theory., authors=DENG Hongwei, HUANG Wei, HU Pulun, GAO Feng, authorsList=DENG Hongwei;HUANG Wei;HU

articleAbstract=回采顺序是采矿工程的重要研究内容之一,合理的回采顺序对采场稳定性和采场生产能力有重要影响.针对老厂13-8^#矿群多层矿体的赋存特点和开采技术条件,采用3Dmine-MIDAS/GTS-FLAC^3D耦合的数值模拟方法,对多层矿体回采顺序进行数值模拟,提出了4种回采顺序优化方案：下向下行式、下向上行式、上向下行式、上向上行式,并从应力场、位移场、塑性区3方面综合考虑,得到了4种回采顺序优化方案的模拟结果;运用基于指标满意度的多指标综合评价模型对模拟结果进行满意度分析.结果表明,4种回采顺序优化方案的多指标综合满意度分别为0.684,0.641,0.653和0.683.其中,上向上行式开采方式的满意度为0.683,因此,上向上行式开采在理论上可行.,
