The transformation of the stress condition of embedded border diastrophic bloc rock of the «pillar-working» system is considered, in combined action of geostatic tension, lateral and transversal tension wave, generated by rock bump. It is supposed that the tension wave front are parallel to the adjacent strata media discontinuity. Under this condition, in the article the influence of the critical tension levels on the roof and pillar rocks stress condition.
