established an elastoplastic softening damage model for soft coal seams during hydraulic fracturing, which takes into consideration the lower elastic modulus and tensile strength and higher pore compressibility
and plastic deformation.

When the effective stress was 5 MPa or 6 MPa, the stress sensitivity coefficient and pore compressibility
factor fluctuated and decreased gradually, and the permeability damage rate varied slowly.
