Mechanism of Seam Floor Water Inrush in a Special Geological Structure Zone and its Application to Water Control in Coal Mining
Based on the principle of solid-fluid coupling, the paper studied on the water inrush phenomenon occurring in coal mining above confined aquifers under special geological conditions and analyzed the mechanism of hydraulic-mechanics of the coupling and interaction between the stress field of surrounding rock and the fluid field of structural zone in the process of mining. A mathematical model of solid-fluid coupling was set up. With numerical simulation, the author described the behaviors of the stress field and fluid field when water inrush happening at floor structural zone due to the influence of dynamic mining pressure. The conclusions are significance to water inrush control for all kinds of mines that are confronted with seam floor water pressure threat.
