矿区整合条件下复杂开拓系统整合优化方案研究OA

Luoba lead-zinc mine,as a multi-mining area integrated mine,has many prominent problems such as multi-pit organization production,multi-stage inclined shaft lifting and wide underground operation points,which lead to more underground supporting personnel,low efficiency and low transportation cost.By putting forward four integrated optimization schemes of development systems and making detailed technical and economic comparison,the transportation system scheme with blind shaft,skip incline and ramp as the core is finally selected to break the production status quo of each pit opening,and integrate the mine into one body for centralized lifting and transportation.It improves the transportation efficiency,reduces the number of workers,saves and improves the cost,and reduces the difficulty of management.
