Evolution Laws of Stress–Energy and Progressive Damage Mechanisms of Surrounding Rock Induced by Mining Disturbance

The rock burst induced by the mutual disturbance of mining and excavation is significantly influenced high static load stress external dynamic disturbance. In this paper, evolution characteristics progressive damage mechanism surrounding in process are systematically studied. results show that can be roughly divided into three stages: rapid rise early stage, continuous step-like decline middle slow late stage. parallel mining, overlying movement above goaf shows sequence horizontal penetration tiny fissures—fracture intensification transition to stratification—non-coordinated caving middle–low rock—obvious cracks upper key layer. Only under quasi-static loading action does layer not reach breaking condition. wave side heading face which close focal point affected disturbance, acceleration duration short, attenuation relatively fast, so it area prone earliest impact failure conclusion helpful deepen understanding coal excavation.
