Abstract Based on a comparative study of the effects of various geophysical exploration methods over the known goaf of the Shuiquan coal mine run by China Coal Corp., this paper sums up the response characteristics of these methods under the same geoelectric conditions, generalizes three kinds of anomalies in goaf of the working area, points out the optimal combination of the geophysical exploration methods, and suggests reciprocal verification of integrated geophysical exploration methods in the detection of goaf.
