Non-Darcy seepage and stopped floor water inrush prevention

Using Forchheimer and non-Darcy seepage theory, revealed the mechanism of water inrush from the structure of nonlinear dynamics system instability perspective. Research shows that: Mine water inrush is related to the porosity of rock, particle diameter, mechanical properties of penetrating liquid, and the velocity of flow etc. The smaller of porosity and particle diameter, the larger of Reynolds number for causing loss of stability of seepage, i.e. the steady state is not easy to lose; otherwise, the larger porosity and particle diameter, the smaller of Reynolds number for causing loss of stability of seepage, the steady state is easy to lose.
