摘　　要：对不同粒度煤样瓦斯解吸衰减系数以及解吸强度进行了实验室考察,探讨了粒度对解吸强度的影响。通过对街洞矿区碎屑状煤芯瓦斯解吸规律的非线性拟合,对各解吸模式的损失量与用计算方法所求得的损失量进行了比较。最后,对各解吸模式测得的瓦斯含量与间接法所测瓦斯含量进行误差比较,提出了适合街洞矿区碎屑状煤芯的瓦斯解吸模式。Different size of coal gas desorption attenuation coefficient and desorption intensity of the laboratory study, Discussion on the size of strength of desorption. Through nonlinear fitting on clastic coal core gas desorption laws in Jiedong mine, compared each desorption model of the loss to the loss of volume by calculation methods. Finally, compared the measurement error about use the measured desorption model of the gas content and the gas content measured by the indirect method, raised a suitable gas desorption model of clastic coal core in Jiedong mine.
