摘要
为了掌握煤岩表面电磁改性过程中的瓦斯吸附变化规律,分析了不同频率、电压电磁场对煤层瓦斯渗透性、流量和抽放率的影响并进行了数值模拟,结果发现:外加电磁场的煤层的渗透率随频率和电压的变化满足线性关系;外加交变电磁场后,煤层瓦斯的瓦斯流量增加了15.56%。
In order to master the gas adsorption variation law during the electric magnetic modification process on the coal and rock surface, the paper analyzed the different frequency and electric voltage electric magnetic field influenced to the seam gas penetration, flow and drainage rate and had a numerical simulation. The results showed that the seam penetration rate of the additional electric magnetic field could meet the liner relationship with the variation of the frequency and electric voltage （electric field strength）. With the additional AC electric magnetic field, the specific flow of the seam gas could be increased by 15.56%.
