平朔井工二矿回采10号煤可行性分析

Feasibility analysis on mining No.10 coal in Pingshuo NO.2 underground coal mine

通过分析平朔井工二矿9号和10号煤层间夹矸厚度分布以及煤层间赋存情况,在10号煤层筛分浮沉试验报告以及研究不同洗选工艺下生产的商品煤煤质的基础上,分析了回采10号煤加工成平8和平9 2种商品煤所产生的收益、回采成本以及10号煤的洗选成本,结果表明回采10号煤经济可行。

By analyzing the distribution of gangue thickness and occurrence condition between No.9 coal seam and No.10 coal seam, on the basis of No.10 coal seam screening and floating test report and commercial coal quality under different washing technology, the author analyzes the benefit and mining cost and washing cost of mining No.10 coal process to No.8 and No.9 commercial coal. Results show that mining No.10 coal is economical and feasible.
