The Surface Mining Control and Reclamation Act of 1977 (SMCRA) requires under-ground coal mine operations to prevent "material damage" to renewable resource lands caused by subsidence.

Although data on the subject are limited, an attempt is made to present quantitative guidelines to distinguish between moderate and severe damage due to subsidence.
