摘　　要：在跳汰生产工艺中,煤炭是在由煤泥和水组成的悬浮液中进行分选的。为模拟实际分选环境,将煤炭在空气中的数质量组成换算为在相应密度悬浮液中的数质量组成,绘制出原煤可选性曲线,绘制方法和原理不变,这样所得到的原煤可选性曲线更切合实际。In coal jigging washing process,coal is washed in suspension composed of coal slime and water.Owing to simulating actual separation surroundings,it is necessary to convert coal quantity-quality composition in air into that in suspension with corresponding density and then washability curves can be plotted with plotting procedure and principle in constant.The washability curves obtained in this way is more practicable.

关 键 词：原煤可选性曲线 数质量组成 洗水密度
