The article assesses the impact of repeated blasts on the stress-strain state of the shotcreting support, which negatively affects the bearing capacity of the support and can lead to the formation of local rock falls in places of significant degradat

Purpose. The practice of using shotcrete for fastening mine workings has revealed the disadvantage of this method. It consists in the fact that a layer of concrete adheres to the mesh, not reaching the working surface, thereby forming voids. The solu
