摘　　要：煤作为一种多孔介质,含有瓦斯的形式是表面吸附,较高的瓦斯含量说明煤中具有较高的吸附潜能。吸附瓦斯转化为游离状态后,才能释放出破碎和抛出煤的能量,因此瓦斯解吸过程对煤与瓦斯突出起到重要作用。从能量的角度,基于煤样的冲击破碎实验,得到煤体破碎功新的数学模型,对煤与瓦斯突出的预测与防治,具有重要的理论价值。Coal as a porous medium, the form of gas containing gas is surface adsorption. The higher gas content indicates that the coal has high adsorption potential. After the adsorption gas is transformed into a free state, the energy of crushing and throwing coal can be released. Therefore, the gas desorption process plays an important role in coal and gas outburst. From the perspective of energy,based on the impact crushing experiment of coal samples, a new mathematical model of coal crushing energy is obtained, which has important theoretical value for the prediction and prevention of coal and gas outburst.
