摘　　要：为了研究构造煤的解吸特性,提高在构造煤发育区瓦斯含量测试的精度,选择正高煤矿M51#煤层构造煤作为研究对象,通过自行设计的吸附解吸装置对特定粒度的构造煤在不同的吸附平衡压力下进行解吸特性研究。结果显示,构造煤的解吸速率随着吸附平衡压力的降低而降低,同一吸附平衡压力下解吸速率随着时间而按照规律递减,构造煤的瓦斯解吸量和速率都大于同一煤层的原生结构煤。In order to investigate the desorption characteristics of tectonic coal and improve the accuracy of methane content measurement in tectonic coal development area, selects the tectonic coal in No. M51 coal seam of Zhenggao coal mine. The research on the desorption characteristics is conducted through self-designed adsorption desorption devices for tectonic coal of specific particle size under different adsorption equilibrium pressures. In accordance with the results, the desorption rate of tectonic coal reduces with the decrease of adsorption equilibrium pressure; under the same adsorption equilibrium pressure, the desorption rate decreases with time in the light of laws; and the amount and rate of methane desorption of tectonic coal are greater than these of primary structural coal in the same coal seam.
