矿井动力灾害的地质动力环境分析与评估

Mining dynamic hazard is combined effect of earth crust movement and mining. Various mining dynamic hazard has the same power source - the elastic energy from crustal movement. The relation between mining dynamic hazard and earthquake, tectonic topography and terrain curvature are analyzed from geodynamics and the geodynamics environment was assessment quantitatively. The results show that mining dynamic hazard was controlled by the regional geological dynamic environment. Tectonic contrast intensity, terrain curvature could reveal geological features dynamic environment quantitatively. It has a great significance for mining dynamic hazard prediction. Multi-factor pattern recognition prediction method of dynamic hazards is proposed, which could make the local detection and targeted and effective.
