摘要

The calculated methane content keeps away from real loss methane content with the increasing of loss time and initial desorption velocity data. Small size coal sample's methane absorption and desorption experimental study is carried out under the condition of a certain methane adsorption balance pressure and constant temperature, which the small size coal sample is collected from different coal mines. The experimental data is studied with the methane desorption law of Sun Chong-Xu formula (Q=ati). Relations among coal sample's methane desorption quantity, exposure time and methane desorption velocity are studied. Then eigenvalues (i) in desorption law (Q=ati) of coal samples with different exposure time is calculated. So the same group coal samples' Eigenvalues calculated with different exposure time are studied. This study provides according for small size coal sample's methane loss value accurate calculation.
