摘要
为了更好的预测预报察哈素煤矿3号煤层的自然发火,在3号煤层采集五组煤样,在实验室进行了煤的氧化升温模拟试验,得出了不同温度下CO、C2H4及其他气体的产生规律,对不同温度范围内CO浓度随温度变化进行了拟合。根据试验结果确定了3号煤层自燃的标志性气体,同时根据察哈素煤矿井下实际,确定了3号煤层自燃分级预警的CO指标。
In order to predict the spontaneous combustion in the No. 3 coal seam of Chahasu coal mine, 5 coal samples were selected from the coal seam and the effect of temperature rising programmed test on process of coal oxidation was studied. The rules of gases emissions such as CO, C2 H4 under different temperature were analyzed and the indicator gases were selected according to the test results. The carbon monoxide was determined according to the actual conditions of Chahasu grading pre -warning index of coal mine .
