Abstarct: The use of intercity train system or subway due to high speed and security, has been increasing in recent years. One of the main steps in using this transportation system is digging the tunnels required for this system. To dig these tunnels, tunnel boring machines (TBM) are usually used because these machines strongly influence the two main parameters in a tunneling project, namely reducing execution time and reducing costs and, By creating a safe environment for personnel, they have the least possible impact on surface structures and the environment. But with all the advances that have been made in these machines, these machines always face dangers that are inevitable. Therefore, an approach should be considered to deal with these hazards so that drilling operations are carried out in the best way and in the shortest time. One of the newest approaches proposed to deal with these hazards in the field of engineering is the resilience approach, which generally refers to the ability of the system to return to normal after an accident. In this dissertation, the resilience of TBM conveyor system of Tabriz metro line 2 has been studied. This system consists of three conveyors that are arranged in series and the length of each conveyor is 7761 meters. baxsed on the relationship used in this dissertation, the main step in resilience analysis is the analysis of reliability, maintainability and supportability, for this purpose, all information and data on downtime due to breakdowns and repairs related to about 15 months of conveyor operation were collected. Statistical analyzes were performed on the data and the values of reliability, maintainability and supportability were calculated. The resilience values of the organization and the efficiency of prevention and health management technology were also analyzed for 80 to 95% sensitivity values due to the unavailability of information, according to the opinion of experienced professors and experts. The analysis showed that the resilience of all three conveyors in the period of 200 hours after starting work is more than 60%, which is a sign of high resilience of the conveyors. The resilience of the whole conveyor system also showed that the resilience for the situation where the amount of resilience of the organization and the efficiency of prevention and health management technology is 95% is more than 70% and for the case that the value of these two parameters is considered 80%, it is more than 25%. The analyzes also showed that the role of organizational resilience and the efficiency of prevention and health management technology increase over time and make a greater difference in the amount of resilience.
