精准配洗模式在范各庄矿的应用研究

Study on precise mixing and washing mode in Fangezhuang Coal Mine

介绍了开滦范各庄矿通过组建井下煤质数据库,强化各煤层煤质分析,实施分采分运,对比各煤层不同配比情况下回收率差别,实现经济效益最大化的精准配洗做法,提升了精煤回收率,提高了企业经济效益。

It introduces the precise mixing and washing method ofKailuan Fangezhuang Mine by establishing underground coal quality database,strengthening coal quality analysis of each coal seam,implementing separate mining and transportation,comparing the difference of recovery rate of each coal seam under different ratio,and realizing the maximum economic benefit,which improves the clean coal recovery rate and improves the economic benefit of enterprises.
