我矿生产的石灰石产品,其质量要求是:CaO≥50～52％;SiO_2≤2～3.5％。自从1958年投产以来,由于有害夹层和上盘围岩的影响,产品质量不够稳定,矿石损失率高达19.48％,矿石利用率低到64.35％。为了解决上述问题,近二年来,我矿除发动群众重视质量,加强地质工作与采掘计划管理以外,并严格实行了分爆分采与质量中和。因此,在地质采矿技
I mine production of limestone products, the quality requirements are: CaO ≥ 50 ~ 52%; SiO_2 ≤ 2 ~ 3.5%. Since it was put into operation in 1958, due to the influence of harmful interbed and hanging wall rock, the product quality is not stable enough. The rate of ore loss is as high as 19.48% and ore utilization rate is as low as 64.35%. In order to solve the above-mentioned problems, in the past two years, apart from mobilizing the masses to pay attention to quality and strengthen the management of geological work and mining programs, the mine has strictly implemented the procedures of separation and separation and quality neutralization. Therefore, in the geological mining technology
