The height of water flowing zone could be determined by FLAC3D numerical simulation, be calculated by empirical formula, and be measured by water injection test. The comparison of the three methods showed that there was no big height error between the numerical simulation and the water injection test and the results of the empirical formula calculation could be used as a reference. If the three complementary methods were combined together, the height could be determined more accurately, which was important for the guarantee of safety in mines.
