Surface residual deformation mechanism and regularity

摘要：

　　In view of the fact that its difficult to study mine goaf surface residual subsidence regularity through field measurement, potential safety hazard does exist for mine goaf surface utilization.In this article, numerical simulation calculation is used.From the angle of rock mechanics, it points out that surface subsidence is a developing process from rock pressure relief deformation to rock mass compacting subsidence; it reveals the fact that ground surface residual subsidence is a phenomenon that rock mass compacting subsidence shows on the ground surface, for which distribution regularity has been studied.It provides the calculation method and parameters of surface residual subsidence based on the numerical simulation results and field measured data.These findings can be used as theoretical basis for safe utilization of mine goaf surface.
