【摘要】：為了掌握王洼二礦5號(hào)煤上分層遺煤的自燃規(guī)律,通過程序升溫實(shí)驗(yàn)臺(tái)對(duì)5號(hào)煤上分層遺煤與原始煤樣的自燃特性參數(shù)進(jìn)行對(duì)比研究。研究發(fā)現(xiàn)王洼二礦上分層遺煤的耗氧速率、CO產(chǎn)生率、CO_2產(chǎn)生率與放熱強(qiáng)度均要大于原始煤樣且120℃后更加明顯,而上分層遺煤煤樣特征溫度及生成C_2H_4和C_2H_6氣體所需溫度均低于原始煤樣,說明王洼二礦5號(hào)煤上分層遺煤更易發(fā)生自燃,危險(xiǎn)性較大。
[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，
