Abstract: The reinforcement of the rock by bolting system is a frequent process to ensure the stability of the underground gate (mines, civil engineering). Although the reinforcement technology is controlled perfectly, but the description of the mechanical behavior of reinforcement and its interaction with the rock mass are not clearly explained. The objective of our research is to understand, using simulation of laboratory test, the various mechanisms of failure of the reinforcement with cable bolting system and to purpose a more effective reinforcing in static or dynamic conditions in underground gate.
