Abstract

To perform efficient and safe haulage operations in mines, the condition of unsurfaced roads where dump trucks are moving should be regularly investigated, and systematic maintenance should be carried out according to the results. In this study, we developed a smartphone application that can be used to periodically investigate the unsurfaced road conditions in mines. Using the developed application, necessary data can be easily collected on site to evaluate the condition of unsurfaced roads according to the Unsurfaced Road Condition Index (URCI) evaluation system presented by the US Army Corps of Engineers. The smartphone application was tested at several sections of unsurfaced road in the ​​Ilkwang mine, Busan, Korea. The results showed that the field investigation about 7 factors considered in the URCI evaluation system can be conducted through the user interface screen, and the URCI value can be calculated in the field to evaluate the condition of unsurfaced road. The smartphone application developed in this study can be useful for surveying and evaluating the unsurfaced road conditions at the mine site.

광산에서 효율적이고 안전한 운반 작업을 수행하기 위해서는 덤프트럭이 이동하는 비포장도로의 상태를 정기적으로 점검하고, 그 결과에 따라 체계적인 유지보수를 시행해야 한다. 본 연구에서는 광산의 비포장도로 상태를 주기적으로 조사하는데 사용될 수 있는 스마트폰 애플리케이션을 개발하였다. 개발된 애플리케이션을 사용하면 미국 육군 공병대에서 개발한 Unsurfaced Road Condition Index(URCI) 평가 체계에 따라 필요한 정보를 현장에서 쉽게 수집하고, 비포장도로의 상태를 정량적으로 평가할 수 있다. 부산 일광광산 비포장도로 일부 구간의 조사를 위해 개발된 애플리케이션을 적용하였다. 그 결과 URCI 평가 체계에서 고려되는 7가지 인자들을 사용자 인터페이스 화면을 통해 손쉽게 조사하고, 현장에서 URCI 값을 빠르게 계산하여 비포장도로의 상태를 평가할 수 있었다. 본 연구에서 개발한 스마트폰 애플리케이션은 광산현장의 비포장도로의 상태 조사 및 평가를 위해 유용하게 활용될 수 있을 것이다.
