【摘要】 为了进一步研究煤与瓦斯突出过程中电磁辐射的产生机理。采用实验室实验与理论分析相结合的方法,对不同压力瓦斯气体充放过程中煤体产生的表面电位进行研究,对比分析了不同通道间的表面电位规律;并结合摩擦起电、流动电势和压电效应等理论,分析了实验条件下表面电位产生机理。更多还原

【Abstract】 In order to further study the mechanism of electromagnetic radiation in the process of coal and gas outburst.The surface potential is studied in different gas pressure during charge and discharge progress and compared in different channels through the method of laboratory experiments and theoretical analysis;the mechanism of surface potential under laboratory conditions is analyzed combining with the theory of electricity produced by friction,steaming potential and piezoelectric effect,etc.更多还原
