| Abstract: | 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 . |
