Development of Monitoring Technology for Mine Haulage Road through Sensor-Connected Digital Device and Smartphone Application

A system that can acquire and share information about the environment from vehicles using various sensors and smartphones was developed to prevent accidents that may occur on mine haulage roads. A light detection and ranging sensor and an accelerometer in a smartphone were used to determine the road surface conditions at a mining site, and dust and gas sensors were used to measure the atmospheric environment. The GPS function of the smartphone was utilized to obtain the location data of the vehicle, and a smartphone application was developed to collect and share this information. A preliminary test was conducted at Samcheok Campus, Kangwon National University, and a field test at the Samdo mine. The data acquired from each vehicle could be shared in real time. Additionally, by analyzing the spatial distribution of each dataset, sections with rough road surfaces and those with poor atmospheric conditions could be identified. If the technology is further developed and big-data analysis is performed in the future, the developed technology could contribute to improving the mining environment.
