Tail Risk Assessment of Coal Mine Roof Instability Under Small-Sample Constraints Based on D-Vine Copula and TVAE Modeling
Ensuring the stability of coal mine roofs is a critical technical prerequisite for safe underground operations and the structural stability of underground engineering systems in mining areas. However, roof instability is governed by the variability and dependence structure of multiple geotechnical parameters, including...
