MINE GOAF SUBSIDENCE TROUGH PROSPECTED BY COMPREHENSIVE GEOPHYSICAL EXPLORATION

    Graphical Abstract
    • Abstract
  • The formation and influence of subsidence area by mined-out are described briefly,and the geophysical base of the high-resolution seismic survey,the emanation determination method and the in-hole elastic wave CT method are expounded.The application and effects of these three geophysical methods are compared,citing the application examples of the comprehensive survey.
