煤矿底板水害威胁十分严峻，本文研究各种模拟方法，鉴于FLAC3D模拟软件在分析岩体三维结构受力特性方面的突出表现，最终使用了FLAC3D模拟软件，对岩样在渗透实验中的变化进行模拟。并在前期对岩样进行一般力学实验，以保证FLAC3D软件进行模拟所需要的各种物理力学参数。用模拟结果与实际的实验结果进行比对，模拟的结果能够体现出煤田底板岩石裂隙与应力变化之间的相互关系。

The water damage of coal slab is becoming serious. In this paper, we studied various simulation methods. In view of the outstanding performance of FLAC simulation software in the three-dimensional structural analysis of rock mass strength characteristics, we decided to use FLAC simulation software to simulate the changes of the rock samples in the infiltration experiments. And in the early stage by doing general mechanics experiments on rock samples, we can ensure a variety of physical and mechanical parameters with which FLAC software simulation can go on. Comparing simulation results with actual experimental results, we can find that simulation results are basically consistent with the experimental results and the stress-strain changes are basically identical. All above these can be able to reflect the relationship between coalfields rock fractures and stress change.
