Experimental study on deformation and damage characteristics of liquid CO2 freeze-thaw coal
Improving the permeability of coal seam is a common method to improve the efficient extraction of coal seam gas. Using liquid CO2 as fracturing medium to freeze-thaw coal is one of the methods to improve the permeability of coal seam. Liquid CO2 changes the permeability of coal seam by causing defor...
