LIU Peng,JIAO Hong-guang,CUI Jing-yuan(Henan University of Science and Technology Material Science and Engineering institute,Jiaozuo454003,China)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.
