Abstract:
Detecting the position of goaf was very important to manage the geologic hazard in goaf. Based on the difference in electric conductivity between goaf and its ambient rocks, the position of goaf was detected by the means of α-card integrated with high-density electrical methods according to the geologic data. The results showed that abnormally high α-ray intensity pulse readings and apparent resistivity in goaf without filling water were physical geography prerequisite to detect the goaf; the effect of α-card integrated with high-density electrical methods on detecting goaf was fine and the result was reliable.
