A theory permitting the determination of expected surface deformations for planned underground exploitation is proposed and discussed in this paper. The relations between surface s ubsidence and various methods of mining are analyzed, and allowable horizontal .deformations for protected objects, according to the degree of their significance, are reviewed.
