利用煤岩升温变形破坏声电效应实验系统,对不同煤岩样在升温破裂时的声发射、电磁辐射信号进行测试,分析得出煤岩样的声发射和电磁辐射信号在加热升温过程中的变化规律,并且对电磁辐射在相同频率不同位置下的变化规律进行测试.研究结果表明,在加热升温过程中,煤岩样都会发出声发射和电磁辐射信号;煤岩所产生的声发射信号会出现先增大后减小的变化规律,而电磁辐射信号会随着温度的变化而变化,其变化趋势和温度的变化趋势大致相同.%In this paper,the acoustic emission and electromagnetic radiation signals of different coal and rock samples were measured during temperature rise and coal and rock rupture by using the test system of the temperature rise,deformation,rupture,and the acoustoelectric effect of coal and rock samples,through the analysis,the change regularity of the acoustic emission and electromagnetic radiation signals of the coal and rock samples in the process of heating and temperature rise was obtained,and the change regularity of the electromagnetic radiation at the same frequency and different position was measured.The research results showed that in the process of heating and temperature rise,the coal and rock samples would emit the acoustic emission and electromagnetic radiation signals;the acoustic emission signal generated by coal and rock samples would increase first and then decrease,and the electromagnetic radiation signal would change with the temperature change,its change trend was roughly the same with that of the temperature.
