| 摘 要： | 对澄合矿区东西区5#煤样进行了自燃程序升温实验通过实验确定该矿区东西部5#主采煤层煤样的临界温度、裂化温度以及CO,CH4气体浓度与温度关系等自燃特性参数,并进一步分析了两区耗氧速度、C2H6,C2H4等气体的变化规律,对澄合矿区东西区5#煤的煤自燃规律做出了初步的探讨研究结论对该矿区煤自燃预测预报工作有重要的指导意义 |
| 关 键 词： | 5#煤层煤样 程序升温 临界温度 裂解温度 |

| Abstract: | This paper analyzed the temperature programmed test about spontaneous combustion characteristics of coal sample 5# from east and west of Chenghe Mining area.It confirms the limit parameters such as critical temperature;cracking temperature and the concentration change of CO,CH4,etc.Furthermore,the oxygen consumption velocity and the change law of C2H6,C2H4 are determined.According to the experimental results,the law of spontaneous combustion characteristics of coal sample 5# is primarily discussed and it ca... |
| Keywords: | coal sample 5# programmed temperature experiment critical temperature decomposition temperature |
