New prediction models offer hope for mitigating longwall subsidence impacts.
Longwall coal mining can cause ground and surface subsidence, affecting structures and water resources. To reduce these impacts, accurate prediction of subsidence movements is crucial. Prediction models based on the influence function method have been developed for different mining methods and terrains. These models have been tested with real cases to ensure accuracy. By predicting ground deformations and understanding structures, potential subsidence disturbances can be assessed correctly. For large structures, stability and functionality must be considered. Once the causes of disturbances are known, effective mitigation measures can be designed. This systematic approach has been successfully used in many applications.
