中文摘要：

利用Eview软件的数理统计功能,采用均方差回归分析方法对构造软煤电性参数的影响因素进行了定量研究。结果表明：灰分、水分和视密度是影响煤电阻率发生变化的主要因素,电阻率随着灰分的增加而增加,随着水分和视密度的增加而减小,孔隙率和挥发分对电阻率影响较小;介电常数随着灰分和孔隙率的增加而增加,随着挥发分、水分和视密度的增加而减小。煤中的水分和灰分加强了煤的导电性,煤的相对介电常数的主要影响因素是煤的变质程度。

英文摘要：

With the mathematical and physical statistics function of the Eview software,the regressive analysis method of the mean square difference was applied to the quantitative study on the factors affected to the electromagnetic parameters of the tectonic soft seam.The results showed that the ash content,moisture content and visual density would be the main factors affected to the resistivity variation occurred.The resistivity would be increasing with the ash content increased and would be decreased with the moisture content and visual density increased.The porosity rate and the volatile matter would be less affected to the resistivity.The dielectric constant would be increased with the ash content and porosity rate increased and would be decreased with the volatile matter,moisture content and visual density increased.The moisture and ash would increase the electric conductivity of coal,the main factors affected the rank of coalification was relative dielectric constant.
