Electro-mechanical coupling laws for EME memory effect during deformation and fracture of coal or rock
煤岩变形破坏电磁辐射记忆效应的力电耦合规律

We have analyzed the relations between electromagnetic emission(EME) pulse numbers and damage parameters and discussed the EME producing mechanism and electro-mechanical coupling laws of EME memory effect during deformation and fracture of coal or rock,established the EME memory effect electro-mechanical coupling model of coal or rock containing gas deformation and fracture under conditions of equal ambient pressure and triaxial compression,tested and analyzed EME memory effect electro-mechanical coupling law of coal or rock containing gas under condition of uniaxial compression.The results show that the EME memory effect electro-mechanical coupling model of coal or rock containing gas primely reflects the characteristic laws and microcosmic damage mechanism of EME memory effect during deformation and fracture of coal or rock.
