Theoretical calculations based on rock strength of the soft rock roadway approach

In this paper, a new coal mine roadway support strong example for the project, according to the theory of rock strength on the mining area of soft rock roadway surrounding rock properties of the theory. The nature of the roadway surrounding rock, the original supporting manner calculated and analyzed. By theoretical calculations to design a joint mesh-anchor of supporting forms, through on-site observation proved to be the implementation of the mine of soft rock roadway mesh-anchor supporting the success of the joint resolve of the mine high stress of the supporting soft rock roadway problems.
