锡铁山铅锌矿副井提升系统改造

Technical Renovation for Hoisting System of Auxiliary Shaft in Xitieshan Lead-zinc Mine

为了缓解锡铁山铅锌矿斜坡道的运输压力，矿方决定改造现有副井提升系统，使其提升能力达到600～800kt／a。根据副井运行现状，分析提出了3种技术可行的改造方案，通过技术经济优缺点综合比较，确定轻型罐笼配3m^3非标侧卸式矿车为最佳改造方案，为矿山实施副井提升系统改造提供了技术指导。

In order to alleviate the pressure of ramp transportation in Xitieshan lead-zinc mine, the existing hoisting system of auxiliary shaft was planned for renovation, so as to enhance the hoisting capacity to 600-800 kt/a. According to the present operation status of the auxiliary shaft, three technologic feasible renovation schemes were proposed. By comprehensive comparison of technical and economic advantages and disadvantages, the optimum scheme was determined to use Light-duty Cage with 3 ms non-standard side tipping wagon. This solution provided technical guidance for the mine hoisting system of auxiliary shaft transformation.
