Study of Pilot Zone Construction of Surface Subsidence Monitoring in Abandoned Mines
Surface subsidence problems in some abandoned mines have seriously threatened living environment. State of the art on surface subsidence monitoring both at home and abroad is overviewed in the paper. Application conditions as well as merits and drawbacks of multiple monitoring techniques have been compared and analyzed. Survey request and data analysis have been discussed. Methods of early warning on surface subsidence has been probed into, which can provide guidance for pilot zone construction of similar mine geo-environment.
