煤矸石自燃宏观特性的实验研究

摘要

为了对煤矸石自燃进行有效的早期预报，利用程序升温实验，测试了凉水井煤矸石升温过程中宏观自燃特性参数的变化规律。实验结果表明：煤矸石在低温阶段即产生少量的CO、C H4，随着温度的升高，耗氧速度和CO、C H4等气体产生速度呈指数规律增加，该研究为生产现场煤矸石自燃的预测预报提供了科学的依据。%To carry out effective early prediction of the spontaneous combustion of coal gangue ,the paper intro‐duces the temperature programming experiment of testing the variation of macro -characteristics parameters of coal gangue spontaneous combustion in Liangshuijing by ,whose results show that coal gangue produces a small amount of CO ,CH4 in the low temperature stage ,with the increase of temperature ,oxygen consumption rate , CO and CH4 gas generation rate increases exponentially ,which would provide a scientific guidance for the predic‐tion of spontaneous combustion of coal gangue .
