摘要
介绍雪峰水泥集团矿山根据矿石特点实行均化生产的实践及效果。露天矿矿区分布有严重影响水泥质量的高镁矿和含泥矿,在对石灰矿中有用成分CaCO_3和有害成分MgO以及第四系覆盖土(含泥矿)在矿区中分布规律分析的基础上,通过强化搭配生产力度和加强生产过程控制,实行均化生产,既保证了水泥质量,又综合利用了这部分矿石,降低了开采成本。
The harmonic extraction practice according to the ore features and the results in Xuefeng Cement Group Corporation are described. There are harmful ore to cement quality, high magnesium content ore and mud ore, in the opencast pit field. Based on the analysis of distribution of the target mineral, CaCO3, harmful ingredient, MgO, and Quaternary sediment (mud ore) in the mining area, the harmonic extraction is adopted by intensification of ores proportion and operation control, so the quality of cement is not only secured, but this part ores are also utilized, and the mining cost is reduced.
