依据在山西省阳泉市280自燃煤矸石山的温度测定试验,研究了自燃煤矸石山温度的变化特征。研究结果表明:温度水平分布没有规律性,分布极不均匀;垂直方向温度由表及里先升高后降低,大约在7m左右最高,再向里温度开始下降;浅层温度与气温的变化规律一致,具有明显的日变化和季节性变化,深层变化不明显;煤矸石山土壤导热性较低,温度由最高点随距离增加而急剧降低,一个高温区的影响范围一般为10m。
Based on the temperature measurement test of coal spontaneous combustion coal gangue in Yangquan City, Shanxi Province, the temperature characteristics of coal sponge burning coal gangue was studied. The results show that the distribution of temperature has no regularity and the distribution is extremely uneven. The temperature in vertical direction increases first and then decreases, about 7m, then decreases further. The variation of shallow temperature and air temperature With obvious diurnal and seasonal changes, the underlying changes are not obvious; the thermal conductivity of coal gangue hill is low, the temperature decreases sharply with the distance from the highest point, the influence range of a high temperature zone is generally 10m.
