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.
