| Popis: | To deal with a water inrush issue that occurs in deep mines in China with more than one aquifer below the floor, the “down three zone” analysis method was modified to establish a conceptual model to evaluate the risk and mechanism of a water inrush. The model comprehensively considers the mechanical action, hydraulic connection, head loss of multiple aquifers, and an analysis of the complexity of water inrush in a multi-aquifer system to define water inrush conditions and criteria of different water inrush modes. There are four types of water inrush modes in a deep multi-aquifer system: single aquifer water inrush, multi-aquifer linkage water inrush, single aquifer lagging water inrush, and linked multi-aquifer lagging water inrush. Preventive and control measures for each of these are provided, based on: preventing linkage, eliminating hysteresis, preventing an inrush from a single aquifer, and preventing inrushes step by step. |
