Abstract

On the basis of the laws of changing the parameters of the dynamic stress field during the interaction of seismic waves with the mine workings the requirements to the seismic resistant armoring of mine workings in the zones of rock bumps and mass explosions are formulated. The operability of traditional types of anchors under dynamic loads is evaluated. The optimum design of fortification of excavations in the shock-hazardous areas is a combined support from steel-polymer or reinforced concrete anchors with a solid filling of the boreholes with a fortifying composition enhanced by piles of long (up to 3.5 m) reinforced concrete anchors in the place of wave exit on the contour of the excavation. The length of the anchors is chosen according to the tensile stress zone overlap.
