煤岩摩擦电荷感应规律分析
|
摘要
利用自主研制的电荷感应仪,建立煤岩体摩擦电荷感应试验系统.研究了煤、花岗岩、砂岩在摩擦条件下的电荷感应规律.试验结果表明:煤岩体摩擦均能快速产生电荷感应信号,且电荷信号幅值在一定的范围内,花岗岩摩擦产生电荷信号大于煤摩擦产生电荷信号,砂岩摩擦产生电荷信号最小.煤岩体摩擦产生的电荷感应信号小于单轴压缩条件下的电荷感应信号,说明煤岩体摩擦起电只是煤岩体电荷感应信号中具有重要作用的一部分,这对研究煤岩体电荷感应机理有一定的作用.
Using self-developed charge inductor,test system about induced charge of electric friction in coal rock is set up.This paper studied the charge induction law of coal,granite and sandstone in the friction condition.The result shows that coal rock's friction can rapidly produce induced charge signals,and the granite can produce stronger signals than the coal does in a certain range,while the sandstone produces the least.The coal rock produces weaker induced charge signals than it does in uniaxial compression condition.It explains that the coal rock flicts to produce electric charge,but it's just one of the most important parts of induced charge signals of coal rocks.This can make contribution to studying the principle of coal rock induced charge.
