我矿80％以上的设备使用年限较长,性能落后,耗能高,维修量大。为了尽快摆脱这种落后局面,在更新资金紧张的情况下,充分挖掘内部人力、物力、财力的潜力,本着先急后缓的原则,积极采用“三新技术”,进行了有计划、有步骤的更新改造工作。经过几年来的不懈努力,我矿技术装备水平不断提高,为保证生产任务完成奠定了坚实的物质基础。 1.设备更新改造与生产工艺改造有机结合 为了满足我矿深部开拓、生产规模不断扩大的需要,几年来我们依靠自己的力量,对我矿提升系统、选冶系统进行了全面改造。在这一过程中,全部采用80～90年代的新产品,取代了50～60年代的提升机;碎矿、磨浮设备一律采用了90年代高效低耗产品,日处理量由原来的750吨/日,上升为1000吨/日,停机检修时间缩短了50％,备品备件消耗年可节支10万元;采掘单耗由原来的23.64千瓦·时/吨降为21.9千瓦·时/吨,选矿单耗由 I mine more than 80% of the equipment longer service life, poor performance, high energy consumption, large amount of maintenance. In order to get rid of this backwardness situation as soon as possible, we should make full use of the potential of internal manpower, material and financial resources under the condition of renewing the funds shortage and actively adopt the “three new technologies” in the light of the principle of “giving first aid to the relief of post-emergency.” Steps to update the transformation work. After several years of unremitting efforts, I continue to raise the level of mine technology and equipment, in order to ensure the completion of production tasks have laid a solid material foundation. 1. The combination of equipment renewal and transformation of production process In order to meet the needs of deep exploration and production scale expansion in our mine, over the past few years we have relied on our own efforts to comprehensively revamp our mine upgrading system and the dressing and smelting system. In this process, all the new products from the 80s to the 90s replaced the elevators from the 1950s to the 1960s. The crushing and grinding equipment used the highly efficient and low-consumption products from the 90s. The daily processing capacity was reduced from 750 tons / Day, increased to 1000 tons / day, downtime maintenance time reduced by 50%, spare parts consumption can save 100,000 yuan a year; mining unit consumption from the original 23.64 kWh / ton down to 21.9 kWh / ton, Mineral consumption by
