【摘要】：为揭示煤中瓦斯解吸过程中加载微波作用对解吸特性的影响,分析探讨了微波辐射促进煤层瓦斯解吸的基本原理,研制了微波作用下煤中瓦斯解吸实验装置,对微波间断加载作用及无微波作用条件下煤中瓦斯解吸特性进行了对比实验研究。实验表明:微波作用对煤中瓦斯解吸具有明显的促进作用,微波作用时间越长,解吸量越大,解吸率越高。在微波作用40 s条件下,微波间断加载作用使得煤样瓦斯解吸量增加290%,解吸率达到87%,解吸速度最大提高率为1 020%。
[Abstract]:In order to reveal the effect of microwave loading on the desorption characteristics of coal gas in the process of gas desorption, the basic principle of microwave radiation promoting gas desorption in coal seam was analyzed and discussed, and the experimental equipment of gas desorption in coal was developed under the action of microwave. The characteristics of gas desorption in coal under microwave intermittent loading and without microwave action were studied in this paper. The experiment shows that microwave has obvious promoting effect on gas desorption in coal. The longer the microwave action time is, the larger the desorption amount is, and the higher the desorption rate is. Under the condition of microwave for 40 s, the desorption rate of coal sample gas was increased by 290%, the desorption rate was 87%, and the maximum desorption rate was 1.02% under the condition of microwave intermittent loading.
