## 1 Introduction: The Development of the Mining Industry and the CBTC System
[18; 19] around 2019, they focused on the safety protection and communications of the CBTC system, and they improved the CBTC system's wireless communication system by the Q-learning method based on LTE-T2T and obtained excellent application results. Recently, [PERSON] et al. [20] focused on combining the CBTC system with artificial intelligence computing (AI Computing). The CBTC system has been used in the above-ground Urban Rail Transit always. In 2015, [PERSON], [PERSON], and [PERSON] [21] thought that the CBTC system is suitable for the above-ground urban traffic monitoring, and they also believed that the operation of the CBTC system in urban traffic is a process of trial and error, because the monitoring of above-ground traffic can reduce the error of the monitoring conveniently by artificial reconnaissance and surveillance. Unlike the above-ground Urban Rail Transit, the monitoring of the underground rail transportation is not susceptible to the artificial reconnaissance and surveillance because of the intricacies of the underground rail traffic. As well, the above-ground traffic control system is mainly to ensure the safety of the traffic and the train departure planning, but it is different in the underground mine rail transportation. In general, the above-ground traffic control system is mainly for the service of passengers, and the underground mine rail transportation is mainly for transport efficiency. Therefore, if the CBTC system is to be applied to underground mines, it is necessary to make some functional changes to the CBTC system. At present, the CBTC system is a relatively advanced control system for the above-ground vehicles, which is applied to urban rail transit lines in various countries even developing countries. Years ago, [PERSON] et al. [22], [PERSON], [PERSON], and [PERSON] [23] all paid attention to the running cost of the CBTC system and explored the possibility of its application in cities of developing countries such as China. For the current CBTC system, the train control center that coordinates and manages all trains running on the line is at the top level of the CBTC system, including the ATS (Automatic Train Supervision) system. [PERSON] et al., [24] researched the anti-interferenceability of the CBTC system to optimize the Supervision Function of the ATS system in the year 2020. The Data Communication System transfers data between modules, including wired and wireless communication network equipment. In 2018, [PERSON] et al. (2018) had already made a great breakthrough on the Access Point Deployment Optimization in the CBTC Data Communication System, and they emphasized the importance of the Data Communication System as the signaling medium of the CBTC system. Additionally, individual vendors have Data Communication System independence as subsystems. The on-board system includes the ATP (Automatic Train Protection) system, the ATO (Automatic Train Operation) system, man-machine interface, and so on. The internal system of the station includes the zone controller system, data storage system, CI (Computer Interlocking) system, and so on. The unified operation of these systems is able to realize the interlocking and calculation of the station and the train. The transponder and axle counting system of the on-board system are installed beside the track (on the track side) to realize the real-time monitoring and position calibration of the incoming and outgoing trains. In 2013, [PERSON] et al. (2018) raised the importance of the overall coordination of the CBTC system; only through the combined operation of these systems can the functions of train safety protection, automatic driving, driver's communication and interaction be realized. Figure 1 shows the CBTC system's structure. Figure 1: The structure of the CBTC system. The ATP system (Automatic Train Protection), the ATO (Automatic Train Operation) system, and the ATS (Automatic Train Supervision) systems are the three most important subsystems to ensure the operation of the CBTC system.
