摘　　要：为研究瓦斯水合物的热量传递机理,基于瞬态热线法原理,建立一套实验设备对瓦斯水合物及纯甲烷水合物的导热系数进行了测试。结果表明,实验所选瓦斯气体生成水合物的导热系数与甲烷水合物导热系数均随温度的升高而升高。该研究从瓦斯水合物的热物性因素方面论证了对煤矿抽采瓦斯进行水合固化分离后以NGH(水合物储运)形式进行储运的可行性。This paper is an effort to study the heat transfer mechanism of gas hydrate by developing an experiment apparatus based on the principle of transient hot-wire method in order to measure thermal conductivity of methane hydrate and gas hydrate. The results show an increase in the thermal conductivity of the selected gas hydrate formation and methane hydrate due to the increasing temperature. From the as- pects of thermal factors of gas hydrate, the study verifies the feasibility of gas storage and transportation in the form of NGH （natural gas hydrate ） following the hydration solidification and separation of coal mine gas.
