为了评价张双楼煤矿9煤的底板突水，根据-350m和-500m两个水平的工作面的煤层底板地质特征，运用快速拉格朗日法对底板的采动效应进行了数值模拟，分析了采动过程中底板岩体应力场、塑性区的分布，通过建立采场底板破坏深度应力解析模型求得底板破坏深度值，认为底板破坏深度值介于两种方法得出值之间更为合理，研究结果为底板水害防治提供了理论依据。

To evaluate Zhangshuanglou Coal Mine floor 9 coal of backplane bursting water, according to the geological features of seam floor at -350m and -500m level working faces, the numerical simulation was made by using fast Lagrange law on backplane of mining moving effect, the stress field and plastic district distribution of backplane rock body in mining moving process were analyzed. Through establishing mining field backplane damage depth stress resolves model, backplane damage depth value was got. And the backplane damage depth value between two species methods is more reasonable. Research results provided a theoretical basis for floor water hazard control.
