摘要
本文概述了荆各庄矿主采煤层 (9层煤 )的地质概况 ,介绍了煤自燃倾向性鉴定原理和方法 ,通过对采自不同地点的煤样进行自燃倾向性实验 ,推测出不同区域的自然发火情况。
in this paper,the general geological situation of coal seam in Jinggezhuang coal mine is summarized and the appraisal principle and method of coal spontaneous combustion tendency is introduced. Through the experiment of coal spontaneous combustion tendency made with the coal samples taking from differdnt spots,the situations of spontaneous combustion in different area are inferred.
