摘要:
为了研究微波场连续-间断辐照作用对颗粒煤瓦斯解吸特性的影响，通过自制的实验装置，分析研究了微波连续-间断作用10 ,20 ,40 s及无微波作用下的构造煤颗粒瓦斯解吸量及解吸速率变化规律，并采用水浴加热装置模拟微波产生的热效应，研究了微波热效应在促进煤粒瓦斯解吸中的影响。实验结果表明：在微波连续作用时间内，瓦斯解吸量和解吸速率均迅速增大，然而随着时间的延长衰减较快，最终瓦斯解吸量趋向于一定值，微波连续-间断辐照作用下的瓦斯解吸量是无微波加载作用下的1.83～3.93倍；微波产生的热效应对瓦斯解吸影响较为显著，权重达82%以上，然而其非热效应的影响也不可忽视。实验方法与结果可望为促进构造瓦斯解吸、降低煤层突出危险性提供参考。
Abstract:
In order to study the influence of continuous-interrupted radiation effect of microwave field on the gas desorption characteristics of coal particle, the change rules of gas desorption quantity and desorption rate of tectonic coal particle under the continuous-interrupted microwave radiation of 10 s, 20 s, 40 s and without the microwave radiation were studied and analyzed based on the self-developed experimental apparatus. The thermal effect produced by the microwave was simulated by using the water-bath heating device, then the influence of thermal effect of microwave on promoting the gas desorption of coal particle was studied. The results showed that in the continuous action time of microwave, both the gas desorption quantity and desorption rate increased rapidly, but they attenuated more quickly with the extension of time, and finally the gas desorption quantity tended to a certain value. The gas desorption quantity under the continuous-interrupted microwave radiation was 1.83~3.93 times of that without the microwave radiation. The influence of thermal effect produced by microwave radiation on gas desorption was obvious, with the weight of more than 82%, however, the influence of non-thermal effect could not be ignored. The experimental methods and results can provide reference for promoting the tectonic gas desorption and reducing the risk of coal and gas outburst.
