Mine water inflow budget is an important part of hydrogeological engineering in mining area. Different hydrogeological conditions require different budget methods. According to the hydrogeological parameters obtained at different stages, it is of great significance to select the appropriate method to calculate the more accurate mine water inflow. This budget is based on the pre-mining and post-production parameters of the No. 12 minefield in the Burqian mining area, Tuokexun County, Xinjiang. The budget is compared with the large mine method, the narrow trench method, and the analogy method. Finally, the large mine method is selected and the budget results are better.
