摘要
根据汝箕沟煤的煤岩和煤质特征、热分析特征和煤的低温自燃特性实验结果，对汝箕沟煤层露头的供氧条件及蓄散热条件进行分析，得出了煤层露头的自燃特性及治理方法。
Coal 2 -2 in Rujigou Coal Field is a kind of good quality anthracite.It is low in sulphur and phosphorus,and high in caloricity.According to analysis,the coal is rich in pores,in which CO and CH 4 usually is adsorbed on the interface,and the coal is less combustible.Further study shows that the shortest ignitable term is about 210 days.And the oxygen consumption speed of the coal is about one order of magnitude lower than that of combustible coal.At last,in terms of the analysis about the conditions of the heat accumulation and heat scattering in the crop coal,the authors put forward the features of spontaneous combustion of coal 2 -2 .
