白银铜矿自投产以来尚未达到原设计100万t的生产能力。文中对影响达产的诸因素进行了分析,指出年产100万t矿石在技术上受到限制,在经济上也不合理。同时,通过中段矿块生产能力计算和作生产能力平衡图等,认为该矿以年产矿石75万t为宜;并用经济合理的服务年限、合理的中段下降速度和新中段的准备进行了验证,提出该矿必须进行适度的技术改造,才能保证在服务年限内稳产75万t/年。
Since the production of silver-copper mine has not yet reached the original design of 1 million t of production capacity. The paper analyzes the factors affecting production, and points out that the technology of producing 1 million tons of ore per year is limited and economically unreasonable. At the same time, through the middle section of the production capacity of lumps and production capacity for the balance map, that the ore to an annual output of 750,000 t of ore is appropriate; and with a reasonable length of service, a reasonable rate of decline in mid-section and the preparation of the new mid-validation , Put forward that the mine must carry out appropriate technological transformation in order to ensure a stable production of 750,000 t / year within the service life.
