Application of Geophysical Exploration Technology in Coal Mine Goaf Management
Actively implementing the application of geophysical methods and managing goaf areas is of great value.Considering the development of some mining enterprises,in the context of improper selection and application of comprehensive geophysical methods and lack of control over the location of goaf,there is a high risk of surface deformation hazards.Therefore,based on the management needs of the goaf in the case project,a comprehensive geophysical method combining controllable source audio magnetotelluric method and radon measurement method was selected after understanding common geophysical methods,which can improve detection efficiency and accuracy.At the same time,detailed analysis of the detection data can help grasp the surface deformation mechanism of the 3#goaf and targeted hidden danger prevention strategies were proposed.Finally,the strategy for preventing and controlling surface deformation was implemented in the hope of meeting the development needs of mining enterprises.
