摘要
新月煤矿煤炭自燃一直严重地影响着该矿的正常生产,针对这一情况,我们取新月煤矿5#自燃煤层煤进行实验,通过煤的升温氧化试验确定指标气体CO随温度的变化规律,建立预估数学模型,将观测点的CO浓度转化为温度指数,然后利用温度进行煤炭自燃危险性预测,从而在指标气体和温度监测火灾之间提供新的方法。
spontaneous combustion in Xinyue coal mine has been seriously affecting the regular production of the mine. In view of this situation, we took the coal＇s sample in 5^# spontaneous combustion coal seam to experimental study. The prediction mathe- matical model was found through coal heating- up oxidation test to determine the CO index gas variation law with temperature, which could change observation point CO concentration into temperature index. The temperature could be used to forecast the risk of coal spontaneous combustion. This provides the new method for monitoring fire between the index gases and temperature.
