摘　　要：为对云南某铅锌矿200 m以下探矿工程的提升系统进行优选,提出了吊桥斜井和甩车道斜井两种提升系统,分别阐述了吊桥斜井的结构和调度方式、甩车道斜井的结构与角度计算,并对两种方案的优缺点、工程量和总投资等进行了对比分析,结果表明:两者的工程量和总投资差距不大,甩车道易在斜井岔机处出现矿车跳道现象,跑车事故频频发生,因此甩车道的安全性较差,而吊桥结构的应用经验丰富、技术成熟,且比甩车道更易操作与维护,因此推荐采用吊桥斜井串车提升方案。In order to optimize the hoisting system of the less than 200 m deep exploration project in a lead-zinc mine,Yunnan,two hoisting systems of suspension bridge inclined shaft and dump lane inclined shaft are proposed.The structure and dispatching mode of the suspension bridge inclined shaft,the structure and angle calculation of the dump lane inclined shaft are described respectively,and the comparison and analysis are made from the aspects of the advantages and disadvantages of the two schemes,the engineering quantity and the total investment among others.The results show that the difference between the engineering quantity and the total investment of the two schemes is not large.The dump lane is prone to the phenomenon of mine car jumping at the bifurcation of the inclined shaft,and derailing accidents occur frequently.Therefore,the safety of the dump lane is poor,and the suspension bridge structure has rich experience in application,mature technology,and it is easier to operate and maintain than the dump lane.Therefore,it is recommended to adopt the suspension bridge inclined shaft trip lifting scheme.
