(abbreviated) Introduction. Development of rock mass mechanics . Interrelation between the mechanics of rock masses and the mechanics of contin uous media. 1. Rock Masses Disturbed by Mining. General characteristics o f rock masses. Idealization of the rock mass. Primary stress state. The equation of continuity. The equation of motion. Concept of weightlessness of a rock.

  1. The Elastic State of Rock Around Excavations. The elastic properties of a rock mass. Effect of rock layering upon the form of the equations of state. Equ ation of equilibrium in terms of displacements. Plane state of strain in a rock mass. Systems operating in a plane state of strain. Three-dimensional states of displacement and stress in the vicinity of excavations. 3. The Viscoelastic S tate of Rock Around Excavations. Rheological properties of rock masses.

Plane strain- and stre ss distributions around excavations. Three-dimensional stress state around excav ations. 4. Geometrical Theories of Rock Mass Movements. Introduction. The effect of an excavation upon a point isolated on the ground surface. The relati on between the surface of influence and the subsidence profile. The plane profil e of a full subsidence trough. Inclination and curvature of the plane profile of a subsidence trough. Determining the horizontal component of displacement and s train. Variation of the shape of a subsidence trough with time. Three-dimensiona l profile of a subsidence trough with two-parameter surface of influence. Three- dimensional profile of a subsi


During the last thirty years, the increasing need for extracting coal from new mining fields, especially from unmined protective pillars and seams that are threatened with rock bursts and rock-gas eruptions, has accelerated the development of research in the fundamental mining discipline known as rock mass mechanics or geomechanics. Generally, rock mass mechanics is concerned with rock mass movements and with the phenomena accompanying them. Extensive theoretical, laboratory, and in-situ investigations have resulted in considerable achievements in the field of rock mass mechanics. It is impossible to include all these achievements in a single monograph, and therefore in the present book the author has attempted to contruct a synthetic mathematical description of the rock mass movements and of the strain and stress state induced by mining, in particular when extracting mineral deposits.
