Discussion on Hydrogeological Conditions and Water Inrush (Outburst) Hazard of the Deep Extension and Replacement Project of Qingping Phosphate Mine

This study aims to address some weak aspects regarding the hydrogeological conditions, water influx prediction, and mechanism of water influx in the 1017-meter tape inclined shaft of the Qingping phosphate mine deep extension replacement project. Through this research, we can understand the lithology and aquifer characteristics of the main water-bearing layer in the deep extension project, identify possible water channels and their water influx intensity, and predict groundwater influx. Additionally, we can investigate the mechanism of water influx occurrence. These research findings will provide a basis for the hydrogeology of the deposit in the deep replacement project and are of significant scientific importance for the prevention and control of mine water hazards and safe mining of deep phosphate mines in the Qingping phosphate mine. Furthermore, the me-thods and results of this study can serve as a reference for hydrogeological research in similar mining areas.
