中文摘要：

利用自主研制的电荷感应仪，建立单轴压缩条件下煤岩电荷感应试验系统和温度对煤岩电荷感应影响试验系统对煤岩电荷感应进行研究。得出煤岩温度升高能形成热电子发射，使煤岩产生电荷，但煤岩破裂过程中产生的主要电荷不是热电子发射产生的。根据电荷一能量联系定律，提出了煤岩变形破裂过程中产生的电荷信号是因煤岩能量释放而产生的观点。认为煤岩产生电荷量可作为煤岩释放能量的量度。煤岩释放能量越多，产生电荷越多，即测得煤岩电荷信号越强，说明煤岩释放能量越多。还解释了煤岩强度越大，破裂时产生电荷量也越多的现象，解释了不同性质煤岩体，破裂过程中释放能量相同而产生电荷信号不同的现象。可为进一步的研究提供参考。

英文摘要：

Using the self-developed charge inductor, a coal-rock charge induction test system and a temperature effect on coal-rock charge induction test system are developed under uniaxial compression to analyse the coal-rock charge induction. The study points out that the temperature rising of coal-rock can form thermal electron emission, but the main charge in the process of coal-rock fracture is not produced by thermal electron emission. According to the law of charge-energy, the perspective of the charge signal production is that the charge in the process of the coal-rock deformation and fracture is in accordance with the energy released by coal-rock. The more the energy is released by coal-rock, the more the charge is created. It demonstrats that the more energy is the cause for the stronger charge signal in the course of deformation and fracture of coal or rock. The higher the strength of coal-rock is, the more the charge will be created. At the same time, it accounts for the phenomenon that the coal-rock with different properties releases the same amount of energy but produces different charges in the process of coal-rock fracture. It may provide a reference for further studies.
