我矿设计年生产能力为40万t,主井提升系统采用JKM2.25/4(Ⅱ)多绳摩擦提升机,单罐笼带平衡锤提升,从历年的生产情况来看,提升系统是制约生产的瓶颈。为满足公司对矿石不断增长的需求,拟将矿车加高150mm,以提高单车装载量,在原有提升次数基本不变的情况下可增产19.2%。本文根据加 I mine designed annual production capacity of 400000 t, the main shaft lifting system uses JKM2.25 / 4 (Ⅱ) multi-rope friction hoist, single cage with counterbalance lifting, from the calendar year production situation, to enhance the system is to restrict the production Bottleneck In order to meet the company’s growing demand for ore, it is proposed to increase the ore car by 150mm to increase the bicycle load, which can be increased by 19.2% under the condition that the original promotion times are basically unchanged.
