Paper Title:
Water Bursting Mechanism of Coal Floor with Pattern Dynamics
  Abstract

Coal floor water inrush is the reason that the deformation and failure of rock strata in floor is induced by mining stress, cracks gradually develop, grow and accumulate, catastrophe result in forming water inrush passages, finally floor water inrush occurs. Interactions of adjacent damage element and long range correlation in coal floor are simulated by pattern dynamics. The evolution process of floor cracks is simulated by the change of element state, and some criteria are given to judge if the floor will fracture with the change of element state. The obvious characteristics of evolution process of floor cracks are progressive, and cracks make order-disorder distribution at different scales that evolve into order distribution, and finally form water inrush passages.
