Over the past several years,the Jingerquan Mine has experienced a long-term and progressive surface fracturing and deformation which is directly related to the block caving method and then we start our investigation based on this background.The trace of fracturing was based on a series of damage mapping activities and the deformation data was collected by GPS from 2013 to 2016.In this paper,following an introduction to the engineering geology and mechanical properties of the rock mass,emphasis was put on an analysis of the fissures,deformation and stress of surface subsidence.Results reveal the diversity magnitude and structural features of surface movement and ground fissures.In addition,the time dependent behavior is comprehended and the subsidence zone reflects different types of time-displacement curve-regressive phase,steady phase and progressive phase,all these achievements indicate the complexity and diversity of the subsidence zone.On the other hand,stress calculation which inspired from the mechanical model of the cracking of hole wall is carried out,it is meaningful to understand the relation between fracture features,displacement vectors and horizontal stress.
