摘要
为了更好地了解煤层物理化学性质,掌握采空区遗煤自然发火的原因,对采集的煤样进行了工业性分析。煤的真相对密度作为煤自燃倾向性色谱吸氧鉴定实验的关键参数,其实验数据将直接影响吸氧量的测定值,同时也影响划分煤自燃倾向性等级。采空区遗煤和顶板岩石的热导率是研究采空区自燃的一个重要参数指标,为采空区自燃数值模拟提供关键参数。
In order to get a better understanding of the physical and chemical properties of coal seam,and master the true cause of coal and rock spontaneous combustion in goaf,the industrial analysis was carried out for coal samples collected.As the key parameter in the experiment of coal spontaneous combustion tendency.The true relative density of coal,its experimental data will have a direct impact on the determination of oxygen content,but also affect the classification of coal spontaneous combustion tendency.Residual coal and the thermal conductivity of the rock in the goaf is an important parameter to study the spontaneous combustion in goaf,these factors can provide key parameters for numerical simulation of coal spontaneous combustion in goaf.
