Abstract:The authors selected three kinds of methods(transient electromagnetic method,controlled source frequency magnetotelluric method and radon gas survey)to conduct large quantities of experiments in the goaf exploration of the Jincheng coal mine. On the basis of exploration effects, the advantages and disadvantages as well as the applicable scope of the three methods were summarized, which is helpful to method selection in goaf exploration in the future.
