Abstract

The standard work report for trucks was developed that records data on truck haulage operations in open-pit and underground mines, and to evaluate the performance of haulage operations. Work reports used in 5 mines in Korea was secured and analyzed, and items to be included in the standard work report were determined. By analyzing the formulas for key performance indicators (KPIs) proposed by the Global Mining Guidelines Group (GMG), it was possible to determine how to record time-related data. After selecting a limestone underground mine as a research area, the performance of haulage operations was evaluated using a standard work report. As a result, in terms of truck availability, uptime was 46.7%, and both physical and mechanical availability were 100%. In the case of utilization, use of availability was 88.2%, the asset utilization was 41.1%, and operating and effective utilization were 88.2% and 79.2%, respectively. Also, in terms of efficiency, operating efficiency was found to be 89.9%.

본 연구에서는 노천 및 지하 광산의 트럭 운반 작업에 대한 데이터를 기록하고, 이를 이용하여 운반 작업의 성능을 평가할 수 있는 표준 트럭 작업 일지를 개발하였다. 국내에서 가행 중인 5곳의 광산에서 활용하고 있는 작업 일지를 확보하여 분석을 수행하였고, 작업 일지에 포함되어야 할 항목들을 결정하였다. GMG (Global Mining Guidelines Group)에서 제안한 핵심성과지표(KPIs)들의 산정식을 분석하여 차량 운행시간을 기록하는 방법을 결정할 수 있었다. 국내의 석회석 지하 광산을 연구지역으로 선정한 후 표준 트럭 작업 일지를 이용하여 운반 작업의 성능을 평가하였다. 그 결과, 트럭의 가용률 측면에서 가동시간이 46.7%, 물리적 가용률과 기계적 가용률은 모두 100%로 나타났다. 이용률의 경우, 가용장비 이용률이 88.2%, 자산 이용률이 41.1%, 운영 이용률과 유효 이용률은 각각 88.2%와 79.2%로 나타났다. 효율성의 경우에는 운영 효율성이 89.9%로 나타났다.
