Abstract: Analysis the influence factors of mine water, analysis mine mining ground pressure of the surrounding rock mass in the process of change, it is concluded that mining depth affect the mechanism of water. On the principle of hydrology geologic analogy method, combining with an instance of two groups of statistical data, the application of deep analogy method and SPSS software function fitting, it is concluded that the influence of the mining depth of mine water inflow. From hydrogeology, geologic structure, orebody occurrence conditions, mining methods, physical and mechanical properties of ore-bearing rock, the natural environment factors analysis of the influencing factors of mine water burst. Combined with haim's law, excavation stress range explains the relationship between mining depth and pressure changes, it is concluded that mining depth affect the mechanism of water. The fitting results show that the external factors such as karst fracture, use a variety of engineering analogy method, choose the optimal forecast, has the superiority.
