甘井子矿为一大型露天石灰石矿。生产过程全部机械化。它的产品,主要供应给鞍钢作冶炼熔剂。由于冶炼生产对矿石质量的要求,矿山中产生了质量中和问题。所谓“质量中和”,就是通过地质、设计、计划和生产操作的一系列工作,将矿体中含CaO,SiO_2高低不均的Ⅰ、Ⅱ级品矿石互相混匀。使其CaO,SiO_2的含量达到理论计算的平均品位。三年来,矿山在这一方面做了一些工作,也取得了一定的成绩:矿石产品质量全部达到了冶炼的要求。
Ganjingzi mine is a large opencast limestone mine. All mechanized production process. Its products are mainly supplied to Angang for smelting flux. As the smelting production of ore quality requirements, the mine has produced a problem of quality and. The so-called “quality and” is through geological, design, planning and production operations of a series of work, the ore body containing CaO, SiO2 uneven grade Ⅰ, Ⅱ grade ore mixed with each other. So that the CaO, SiO 2 content reached the theoretical average grade. In the past three years, the mine has done some work in this respect and has also made some achievements. The quality of ore products has all met the requirements of smelting.
