Elastoplastic problem about stretching of a plane with a circular hole

Article preview

Elastic – plastic balance of the hills massif is examined under the Stavrogin's condition of destruction under symmetric boundary conditions in view of the heterogeneity of a file arising at artificial freezing of friable watery breeds with the help of freezing columns. Formulas for definition of pressure and movings to plastic and elastic areas are received. The border between elastic and plastic areas is found. The area of existence of the decision is determined.

Elastoplastic problem of stress distribution around mine workings with consideration of only the limit state

Article preview

The elastic-plastic equilibrium of a rock massif is considered taking into account only the forbidden state. Formulas for determining stresses and displacements in the elastic and forbidden zones are obtained. The boundaries between the forbidden zone and the elastic zone are found.

On the delaminability of unstrengthened heavy coal seam roofs

Article preview

In the literature, the impact of unstrengthening on the stratification of rocks of heavy roofs has not been given enough attention. As is known, the delamination of layered rocks of the roof of workings significantly reduces their bending stiffness, which eventually leads to a significant increase in the normal to the layering displacements of layers between the layers and the formation of limiting zones. In this regard, prediction of the stratification of unstrengthened in combination with hydraulic treatment of rocks of heavy roofs is important, as it is used in selecting the optimal parameters of coal deposits development systems, providing the necessary operational mode of the working chamber, as well as in solving other important geomechanical problems.

On the stratification of anisotropic interbedded rocks

Article preview

In this paper, the method developed by Professor S.T. Kuznetsov for calculating the delamination of sedimentary roof rocks with close elastic characteristics is proposed to be transferred to transversal-isotropic interlayered rocks. The issue of predicting possible patterns of delamination and detachment of interbedded rocks with elastic anisotropy is very important, since the obtained information is used in selecting and properly placing high-capacity complexes and mechanized supports, as well as in solving other important problems of mining geomechanics.

On the effect of humidity on the stratification of interbedded rocks

Article preview

Based on the use of the special limit state condition, studies were conducted on the effect of moisture on the stratification of layered interbedded rocks for the case of overworked and then underworked interbedded rocks. The researchers paid insufficient attention to the effect of humidity on the stratification of interbedded rocks. As is known, the stratification of stratified rocks of the roof of mine workings significantly reduces their bending stiffness, which eventually leads to a significant increase in normal to the layering displacements of interlayered layers and the formation of limit zones. In this regard, prediction of the stratification of interbedded rock, with account of moisture, is important, as it is used in selecting the optimal parameters of the passports of mine workings, providing the necessary operational mode of mine workings, as well as in solving other important geomechanical problems.
