通过对焦作矿区煤样的瓦斯解吸规律研究，找出了采用解吸法测定煤层瓦斯含量时推算损失量误差的原因，提出了完善推算损失量的方法。 By studying the gas desorption law of coal samples in Jiaozuo mining area, the reason for calculating the error of loss when determining the gas content of coal seam by desorption method was found out, and the method of perfecting the calculation of the amount of loss was proposed.
