The evolution law of pore characteristics and pore bulk modulus for overpressured coal-bearing formation in Yuwang Minefield

The evolution law of pore characteristics and pore bulk modulus for overpressured coal-bearing formation in Yuwang Minefield

The abnormal high pressure in coal and coalbed methane exploitation will bring danger to exploitation, thus threatening the safety of personnel and property.Six coal samples collected from Yuwang colliery in Yunnan province were analyzed by CT scanning and low-temperature liquid nitrogen adsorption...
