Coal and rock gas permeability teste

Coal and rock gas permeability coefficient tester according to mt223 4-90 determination method of permeability coefficient of coal and rock is mainly used to determine the permeability coefficient of gas to coal and rock
The index directly reflects the difficulty of gas drainage in mine, and provides scientific data basis for reasonably arranging pre drainage time and calculating drainage radius; So as to improve the gas extraction rate
The intelligent gas permeability coefficient tester is an instrument for testing, scientific research and teaching in coal mine gas production laboratories, scientific research institutions at all levels and colleges
The performance characteristics of coal and rock gas permeability coefficient tester are designed intelligently and fully automatically
After sample preparation, the experimental process is completed with one key, and the automatic data calculation results can meet the requirements of coal pillar (rock pillar) test pieces under natural water content, dry state and water saturation state at the same time
