It is widely accepted that the energy consumed for entraining the mixture of gas and coal comes from in situ stress and high pressure gas reservoir in coal [12] [13] [14]
As shown in Fig 10 the diffusion coefficients of coal SJZY and coal SJZR decrease gradually with the desorption process and the main reasons are as follows On the
The results indicate that the amount of pores in the range of 10 20 nm in coal reduces during the pulverization process In the range of 20 30 nm both coals show that the
