摘　　要：通过对一段时期内的矿井原煤在不同水分、不同粒度的情况下进行堆密度、真相对密度的测定,应用Grubbs检验、二元线性回归等数理统计方法,完成所有检测数据的筛选和统计,验证基于煤炭真相对密度的实验数据支撑下,煤炭水分和煤炭粒度对堆密度测定值影响的二元线性关系。By measuring bulk density and true relative density of raw coal under different conditions of moisture and particle sizes through a period,this paper collects and analyses testing data by using mathematical and statistical methods such as the Grubbs test and binary linear regression.It verified the binary linear relationship between coal moisture/coal particle size and bulk density based on the experimental data of true relative density of coal.
