Abstract
In this study, we developed a system to collect and analyze log data related to truck travel times in underground mines using Bluetooth beacons and tablet computers. When a signal from beacons installed at a major underground mine is received by a truck-mounted tablet computer, the beacon information is collected and uploaded to a cloud server. A data processing program integrates the uploaded log data files into a single file, calculating the statistical values for each section of the transport route. The developed system was applied to a limestone underground mine located in Jeongseon, Korea, to diagnose and analyze the transport routes in the study area. As a result of this analysis, it was possible to select sections in which the truck transport time was stable and sections in which it was unstable. Consequently, the transport route could be classified into four types based on the distribution and fluctuations in the truck transport time data. Moreover, it was possible to analyze the causes of the stable and unstable sections through production logs and field staff interviews. The developed system could be used as a tool to improve transport operations by diagnosing and analyzing the truck transport routes of a mine.

Summary
Innovative technologies at the forefront of the fourth industrial revolution include artificial intelligence (AI), drones, the Internet of Things (IoT), 3D printing, robotics, autonomous driving, and big data. These technologies are spreading throughout the industry to improve its productivity and efficiency and are causing major social and economic changes [1,2]. Smart mining refers to the introduction of cutting-edge information and communication technology (ICT) such as the IoT, big data, mobile, AI, and augmented reality (AR), preparing the way for the fourth industrial revolution and new climate change regimes, and to realize eco-friendly, high-efficiency, low-cost, and disaster-free mining sites. An ideal smart mine can be built by gradually utilizing IoT technology [6]
