Today, due to the importance of underground spaces, their maintenance is also of special importance. Rock rock is one of the underground space maintenance systems that increase the strength properties of rock mass and is widely used in underground structures today. Numerical modeling is also an important tool in rock engineering. The choice for a specific numerical method is based on its capacity to show the problems of boundary conditions, material behavior and failure mechanisms of the relevant rock mass. In this project, we intend to develop a new method based on optimizing the maintenance of trenches and oil wells. Which is known as rotational arrangement (rotational arrangement) to use in the arrangement of tunnel stone screws. Specifically, the purpose of this study is to investigate the effect of rotational arrangement method on improving the stabilization of random blocks formed around the tunnel by stone screws using the separate element method. This research is based on real data taken from a cave called Club 2 in southeastern Sweden. For this purpose, we first simulated the discontinuous environment by randomly constructing DFNs, and then we modeled and maintained the tunnel using 3DEC software. Meters is the best way to maintain this space.
