【 摘 要 】

The stress state of a rock mass and support members in the staged advance of two parallel workings is calculated. The feasibility is demonstrated to solve such problems by using the stiffness matrix of the calculation system which remains unchangeable in the development stages. Two versions of mining and construction processes are considered. Specific features of stress-field formation in the support system are discussed. The recommendations on selection of a mining system, best from the geomechanical viewpoint, are worked out and set worth.
