Risk identification and early warning method of old goaf floor Ordovician limestone water inrush based on attention-LSTM and isolation forest

Mine water inrush from the Ordovician limestone aquifer is a major coal-mine safety threat, especially beneath old goaf floors where precursor signals are weak and concealed. This study develops an intelligent early-warning method integrating an Attention-LSTM network and an Isolation Forest model. Five-minute boreho...
