Abstract:Based on the research of geomorphic characteristics and the spatial form of deep goafs in Yinmin copper deposit, the concealed goafs of Dapicao ore-section in Yinmin mining area are developed the geophysical prospecting by using high density resistivity method and EH-4 method. According to the interpreted results, the author hold that the prospecting results of shallow goafs and actual situation has favorable matching-degree, which detected by high density resistibity method. In addition, this results could delineated the spatial-forms of goafs. Besides, the author found that the EH-4 method could detected the space position of goafs, which buried the effective depth is about 1000m, but cannot be measured the morphology of concealed goafs. The accuracy and reliability are improved by comparative analysis of this two geophysical methods, which can provide technical support to the detecting work of goafs.
