The P-wave velocity can predict coal properties and methane adsorption in high-volatile bituminous coals. Higher P-wave velocity is linked to denser coal and less porosity, while lower velocity is associated with more porous coal. Vitrinite content in coal is related to porosity, while inertinite content is linked to density. The P-wave velocity can help predict coal maceral composition and methane adsorption capacity, aiding in coalbed methane exploration and gas prevention in mines.
