| 摘 要： | 龙首矿在“十·五”期间,由于加大了富矿回采力度,使富矿面积相对缩小过快,造成采场下降高度严重失衡。要满足矿石产量的稳产并提高,必须重新设计六角形进路断面规格。本文采用三维有限元数值分析程序,通过现场收集大量的资料,设计了8种方案进行模拟分析。结果表明,龙首矿下向六角形回采进路断面可进一步增大,最优进路断面规格为：底宽305cm,腰宽7m,高6m,断面积31．5m^2,并且分析了充填不接顶距对采场稳定性的影响,为该矿今后的生产提供了科学依据。 |

| Abstract: | The rich ore area in Longshou Mine,during"Tenthfive Year Plan",was dwindled so fast because of strengthening rich ore production that the descent altitude among stopes was outofbalance seriously.To meet the producing and improving of ore output,the hexagon crosssectional dimension must be redesigned.In this paper,using threedimensional finite element method and collecting a large number of data live,have designed 8 kinds of simulation schemes.The results indicate of crosssectional dimension of hexagon stope can be further enlarged and the optimal model of hexagon stope is the bottom width of 3.5 m,the middle width of 7 m,the height of 6 m as well as the basal area of 31.5 m2.Furthermore,the effect on stope stability by the height of nonfilling space in stope was analyzed.The simulation result can offer the scientific basis for production in the future. |
