To improve the mining efficiency of coalbed methane, liquid nitrogen freeze-thawing experiments were performed to improve coal seam permeability and to study its influence on coal pore structure development and mechanical properties. Mechanical properties and nuclear magnetic resonance tests of coal samples were performed with 0, 5, 10, and 15 freeze-thaw cycles of liquid nitrogen. The results show that the number of freeze-thaw cycles caused the change of uniaxial compressive strength and elastic modulus of coal, and
