Description

technical field [0001] The invention relates to the technical field of artificial intelligence and coal mining water disaster prevention and control, in particular to a method and system for predicting coal mine water inflow based on LSTM algorithm. Background technique [0002] Coal mine water gushing is one of the most common disasters that threaten mine safety in the process of mine construction and production, alongside mine gas and fire. In the process of coal mine construction and production, due to the complexity of mine hydrogeological conditions and the limitations of people's cognition of mine water filling elements, mine water disaster prevention and control measures are often not in place or other concealed water hazard conditions beyond people's ability to understand The existence of various types of mine water damage. [0003] At present, the commonly used coal mine water inflow prediction methods can be roughly classified into two categories: deterministic me...
