| 摘 要： | 根据杨庄煤矿的开采地质条件，分别建立了走向和倾向两类基本模型，应用数值模拟方法，模拟计算了工作面不同推进距离和不同切眼长度时，底板的破坏深度、范围及采动底板应力分布。数值模拟与现场应力测试及注水试验结果基本一致。对煤矿底板灰岩水的防治有一定的指导意义。

| 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. |
