coalbed gas into exploited wells. The pore structure of coal sample changes caused by freeze-fracturing were characterized by … freezing were analyzed. Results show that freeze-fracturing can complicate the coal pore structure, and its complexity is … of original pores into larger ones. By comparing the connectivity and seepage space of the pore structure of coal before …
