Study on Mine Water Inflow Prediction for the Liangshuijing Coal Mine Based on the Chaos-Autoformer Model

Water
Mine water hazards represent one of the principal threats to safe coal mine operations; therefore, accurately predicting mine water inflow is critical for drainage system design and water hazard mitigation. Because mine water inflow is governed by the combined influence of multiple hydrogeological factors and thus exhibits pronounced non-linear ...
