Management of rock properties in drilling and blasting processes

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.

To the technique of estimation of activated disturbances at explosive crushing of rocks

Article preview

The work is related to the solution of the problem of predetermined change of properties and states of rocks by surfactants in relation to improving the quality of rock crushing by explosive method. The regularities of the origin and development of cracks in rocks loaded in the surfactant medium are analyzed, the obtained parameters of crack propagation allow estimating the probability of destruction of the rock massif. The questions of determination of perturbations in the medium activated by blasting are considered.
