I conducted a subsidence analysis to evaluate the potential surface deformation resulting from underground coal mining activities. Subsidence is a critical aspect that must be carefully assessed to prevent impacts on surface infrastructure, the environment, and overall operational safety.
While empirical approaches—based on past case studies and established prediction formulas are commonly used as an initial estimate for subsidence behavior, these empirical methods still need to be validated through numerical analysis. In this case, a three-dimensional numerical modeling approach was applied to capture the complex interactions between the mined-out voids, overburden response, and stress redistribution in the surrounding rock mass.
