Abstract
The natural stress-strain state of mining massif is disrupted while mining works is carried on. Different numerical methods can be applied for calculation of parameters stress and strain state in the mining massif: the finite difference method, the finite-element method, the boundary element method, the application of the last of these methods is described in this work. The problem of distribution strains around entries of different configuration, drifted in elastic, homogeneous, isotropic mining massif is described. The indirect method of fictitious stresses and the boundary integral method are used for solution this problem.
