摘 要: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 of 280 gangue pile liable to spontaneous combustion in Yangquan city,Shanxi province,the characteristics of temperature change of the gangue pile was studied.The results showed that level distribution of high and low temperature in 280 gangue pile was irregular,was very uneven,the temperature increased from outside to inside in vertical direction;the highest temperature appeared at about 7m apart from surface,from where to the inner the temperature began to decline;in the shallow zone the variation rule of temperature was similar to that of atmospheric temperature,with obvious diurnal change and seasonal change,but in the deep the temperatures did not change significantly;the thermal conductivity of the soil in the gangue pile was low,he temperature reduced sharply form the highest point along with distance.
