摘　　要：针对传统二维开拓设计模式存在的设计效率低、工作量大和竖井最优参考位置难以确定等问题,开展竖井位置的三维协同设计研究。以广西华锡集团铜坑锌多金属矿为例,从协同开采理念出发,构建由矿量与矿体埋深相结合的三维运输功计算模型;借助三维矿业软件对岩石移动范围进行圈定并给出竖井开拓初选方案;采用集对分析同一度法,以安全性、资源利用率、运输功和经济投资4个评价指标对初选方案进行优选。研究表明:该三维运输功计算模型可从三维角度精确规划竖井的空间最优位置,可为开拓设计提供有益参考。With the rapid development of digital mine,3DMine software has been widely used in mine design institutes.However,for multi-layer gently inclined thin ore group,the traditional two-dimensional underground mining development design mode has some problems,such as low design efficiency,heavy workload and difficult to determine the optimal reference location of development shaft.Under the guidance of the concept of synergetic mining,the 3D synergetic design of shaft location was carried out to accurately plan the spatial layout of the development shaft,improve the efficiency of mining design and ensure the effectiveness of the design scheme.Taking Tongkeng zinc polymetallic deposit in Guangxi Huaxi Group as the engineering background,and referring to the traditional two-dimensional transport work calculation model,considering the influence of ore volume and different burial depth on transport work,a three-dimensional transport work calculation model was established based on straight line distance,and then the vertical shaft development arrangement was optimized and the competition problem of transportation work was dealt with cooperatively.According to the determination method of rock movement parameters recommended by Mining Survey Research Institute in Soviet Union,in the Tongkeng zinc polymetallic mine case,the rock is classified into layered rock mass and rock movement characteristics.Combined with the occurrence form,engineering geological condition,hydrogeological condition,surface topography,geological structure,mining method and rock mass mechanical parameters of the orebody,the rock movement angle of the upper,lower and end of the orebody is determined to be 75%with reference to the actual data of the surface rock displacement of similar mines.With the aid of3DMine software,the scope of rock movement was delineated,and combined with the proposed threedimensional transport work calculation model,the preliminary selection scheme of shaft development was given.The set pair analysis method was used to optimize t
