【摘要】:为了掌握王洼二矿5号煤上分层遗煤的自燃规律,通过程序升温实验台对5号煤上分层遗煤与原始煤样的自燃特性参数进行对比研究。研究发现王洼二矿上分层遗煤的耗氧速率、CO产生率、CO_2产生率与放热强度均要大于原始煤样且120℃后更加明显,而上分层遗煤煤样特征温度及生成C_2H_4和C_2H_6气体所需温度均低于原始煤样,说明王洼二矿5号煤上分层遗煤更易发生自燃,危险性较大。
[Abstract]:In order to master the law of spontaneous combustion in No. 5 coal of Wangwa No. 2 Coal Mine, the characteristic parameters of spontaneous combustion between the coal of No. 5 and the original coal samples were compared with the original coal samples by means of temperature programmed test bench. It is found that the oxygen consumption rate, CO production rate, CO_2 production rate and exothermic intensity of the remaining coals in Wangwa No. 2 Coal Mine are higher than those of the original coal samples and are more obvious after 120 鈩,
