Experimental study on mechanical-charge induction law of coal containing gas under triaxial compression
Abstract：With the self-developed charge-induced equipment, the experimental researched effects of different confining pressure and pore pressure on charge signal during deformation and fracture of coal containing gas under triaxial compression. The results show that as the pore pressure increases, the charge induction signal weakened when the confining pressure is a certain value. The pore pressure plays a weak effect role in the charge induction signal produced during the coal sample deformation and fracture process. As confining pressure increases, the charge induction signal enhanced when the pore pressure is a certain value. The confining pressure plays an enhancement effect role in the charge induction signal produced during the coal samples deformation and fracture orocess.
