摘　　要：为了增加露天矿经济和环保2个方面的额外效益,根据伊敏露天矿实际情况,提出了在开采环节实现优质煤劣质煤区别开采的方法,方法通过煤层及煤质条件分析、优质煤供煤系统及煤层确定、发热量热值分布情况分布、区域条带划分与原煤发热量计算、质煤范围及优质煤量确定等步骤,实现了准确的年度产量预测,帮助了矿山管理者更好地规划生产和销售。结果表明:伊敏露天矿作为优质煤的来源为采用自移式破碎机半连续系统的部分16下煤,且不同年份的优质煤量和优质煤范围差异较大,预测伊敏露天矿2023—2025年优质煤量分别为6.56、1.62、2.75 Mt,增加额外效益分别为5740万元、2406万元、1417万元,可实现露天矿优质煤的单独开采及稳定供应。In order to increase the additional benefits of open-pit mine in terms of economy and environmental protection,based on the actual situation of Yimin Open-pit Mine,a method for distinguishing high-quality coal from low-quality coal in the mining process has been proposed.The method involves analyzing coal seams and coal quality conditions,determining the supply system and coal seams for high-quality coal,distributing the distribution of calorific value,dividing regional zones and calculating the calorific value of raw coal,determining the range and quantity of high-quality coal,and accurately predicting annual production to help mine managers better plan production and sales.The results show that the high-quality coal source of Yimin Open-pit Mine is partially 16 coal using a self moving crusher semi continuous system,and the amount and range of high-quality coal in different years vary greatly.It is predicted that the high-quality coal in Yimin Open-pit Mine from 2023 to 2025 will be 6.56,1.62,and 2.75 Mt respectively,with additional benefits of 57.4 million yuan,24.06 million yuan and 14.17 million yuan,which can achieve independent mining and stable supply of high-quality coal in open-pit mine.
