Status and prospect of coal mine geophysical exploration technology in China

On the basis of coal mine geophysical exploration technology development represented by channel wave seismic method, mine transient electromagnetic method and underground borehole inclinometry, development directions of mine geophysical exploration technology were indicated, which were strengthening fundamental theory studies of mine geophysical exploration method in respects of whole space, multi-field coupling and forward-inversion, improving fine exploration level of mine geophysical exploration in areas of joint inversion for different physical properties and recognition with multiparameter comparison, and developing intelligent and portable mine geophysical exploration equipment with explosion-proof type.
