摘要
以北宿、洛阳等两地高硫煤为样品按照国标(GB/T478-2001)进行了浮沉试验,并对两煤样进行了不同密度级煤的质量(灰分、比磁化率、硫分)状况的测定;结果表明随着密度级的增加,煤的灰分和比磁化率均逐渐增大,而硫分在各密度级的分布同煤种有关,缺乏普遍规律可循,与低密度级相比高密度级高硫煤的煤质普遍较差。
North of slept, Luoyang and so on two places Gao Liumei（ GB/T478 -2001 ）has carried on the vicissitude experiment for the sample according to GB code, and has carried on the different density level coal quality to two coal samples （ash, ratio magnetic susceptibility, sulfur content）the condition determination; The result indicated along with the density level increase, the coal ash and gradually increasing compared to the magnetic susceptibility, but the sulfur content plants related in various densities level distribution with the coal, lacks the universal law to be possible to follow, compares high density level Gao Liumei with the low density level the anthrax to be generally bad.
