Aiming at the problem of low accuracy and difficulty in dynamic prediction of coal face water inflow for coal mine flood control, CCTEG Xi’an Research Institute independently developed a multi-stage dynamic dynamic prediction technology for coal mine workingface water inflow. A multi-stage dynamics dynamic prediction program and software for the water inflow of the working face were also innovated, which realized the rapid prediction of water inflow of the before mining and the dynamic correction during mining. This technology has been promoted and applied in 14 coal mines in 6 coal mine areas including Ningxia and Shaanxi. The accuracy of the water inflow forecast at the applied working face has been improved by more than 15%. This technology has universal applicability in the prevention and control of roof water hazards in Jurassic coalfields in western China, especially in the prediction of water inflow at long working faces.
