Application of the direct variant of the boundary element method in solving geomechanical problems for Starobinskoye field conditions

Article preview

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 influence of technological removing schemes on stress strain state of rock massif was analyzed as applied to Starobinsky deposit on the attenuated stage of mining.

Application of the boundary element method for calculating the parameters of the stress-strain state of a rock massif in the vicinity of workings of different outline

Article preview

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.

Determination of optimal parameters of the limiting state zones of coal in the development of flat coal seams

Article preview

The influence of various factors on the condition of the edge zone of the coal seam ahead of the face during the development of flat seams is assessed. All the variety of factors can be divided into mining-geological and mining-technical. Of mining-geological factors, the greatest influence on the coal deformation in the peripheral zone have such factors as power, depth of development, dip angle, presence of interlayers, of mining-technical - face length, speed of its movement, development system, type and power characteristics of the support, method of rock pressure control.
