Coupling Relationship between Ground Collapse Fracture and Water-Conducting Fracture Zone Development

Abstract

The coupled development of ground collapse fissures and water-conducting fracture zones is the common hazard in mining areas, causing serious threats to mine water control and ecological safety. This study reviews the research progress on collapse fissures and water-conducting fracture zones in domestic and abroad systematically, summarizing their formation mechanisms, distribution characteristics, hazard impacts, monitoring and prevention techniques. Highlighting the development patterns and the two different geological conditions (shallow-buried thick coal seams, karst areas, loess regions), and analyzes the coupling mechanisms of ground collapse fissures and water-conducting fractures in spatiotemporal evolution and hazard triggering. Aiming at limitation of current predictive models and monitoring methods, some new research directions are proposed, including constructing multi-parameter coupling prediction models, integrating satellite-air-ground monitoring, strengthening the studies on lithology-engineering response mechanisms, and coordinating ecological restoration with engineering measures, in order to provide scientific guidance about the mine water hazard prevention and environmental protection under complex geological conditions.
