摘　　要：根据国际标准的平行热线法原理,设计出测定松散煤体导热系数试验装置,给出了其计算方法,并对祁东煤矿的不同粒径及不同含水量的煤质进行了反复试验,结果表明:随着粒径及含水量的增加,煤体导热系数呈上升趋势,且越趋平稳;最后对结果作了详细分析。An experimental device for the measurement of the thermal conductivity of loose coal bulk was designed based on the internationally standardized Hot Wire Method (parallel) theory, its calculation method was derived and repeated tests were carried out on the coal with different particle size and humidity in Qidong Coal Mine. The test results showed that the thermal conductivity is tending to increase and becomes stable with the increase of particle size and water content of coal. Finally, analysis was made on the test results.
