  ABSTRACT: It is the premise of preventing water inrush accident and ensuring mine safety to make clear the development height of water-conducting fracture zone. Based on rock mechanics and hydrogeological parameters of Songxian Gold mine, the height of water-conducting fissure is 8.38 m according to empirical formula method. By using discrete element software UDEC, numerical simulation method and Mohr-Coulomb constitutive model as the plastic yield criterion of rock and soil mass, it is determined that the development height of water fracture zone in stope 050001-07 filling mining of gold mine is about 9 m. Field measurement shows that the development height of the water-conducting fracture zone is 8.12 m. In summary, the height of the water-conducting fracture zone obtained by the three methods is 8.38 m, 9 m and 8.5 m, respectively. It can be seen that the height difference between the numerical simulation and the measured one is 9.78%.
