摘要
在东露天煤矿9号煤层筛分浮沉试验报告基础上,对各粒度级、密度级硫分组成进行分析,并结合选煤厂洗选工艺,利用产品结构优化决策支持系统进行了硫分测算,在以满足市场需求前提下,结合当前售价和硫分优惠政策,分析了所生产商品煤的洗选成本和收益。
Based on the screening and floating test report of No.9 coal seam in East Open-pit Mine, the author analyzes the sulfur content of all levels granularity and density, and carries out sulfur calculation combining the coal prepartion technique and using the support system of product structure optimization. In the premise of meeting market demand, combining the present price and sulfur content preferential policies, the author analyzes the coal prepartion cost and profit of commercial coal.
