Study on the Effect of Mined-Out Region on Ground Subsidence

Abstract:

Longtime existence of the mined-out region brings enormous security potential risk to the residents living in ore area. The model of the mined-out region underground has been established and calculated, and the effect of mined-out region on ground subsidence has been analyzed. The analysis result shows that the deformation of the roof of the mined-out region has significant influence on the ground surface and measures must be carried out immediately. Finally, the rational measures for treating the mined-out region are given to ensure the smooth and safe operation of the follow-up mining.
