Abstract

Mining works executed in deep layer sedimentary rocks, are exposed to large deformation speeds during exploitation, because of rock pressure applied on the walls, the ceiling and bedrock of excavations. In this paper, we aim to find a solution for optimizing the constructive metallic structures, and subsequent linings, through the improvement of the transmission way of loads originating in rock pressure. According to Panet – Sulem support/rock interaction, there is a possibility of guiding rock pressure through constructive support system.
