Abstract: According to the mining geology term in Yangzhuang Coal Mine, two basic models of the strike and dip is established; and applying the method of numerical simulation, seam floor breakage depth, scope and mining floor stress afresh distributing are simulated and computed in the different face advance distance and different set-up room length. Contrasting the stress test and injection test in spot, two results are basically identical. It is shown that the results are useful for prevention and cure of limestone water of coal mine floor.

Key words: numerical simulation, seam floor break, stress afresh distributing, mining effect, Yangzhuang Coal Mine
