트럭배차 방식을 고려한 노천광산 쇼밸-트럭 운반 시스템의 시뮬레이션 = Simulation of Shovel-Truck Haulage Systems by Considering Truck Dispatch Methods

다국어 초록 (Multilingual Abstract)

This paper presents a case study that performed simulations on shovel-truck haulage systems in open-pit mines by considering fixed and real-time truck dispatch methods. A limestone open-pit mine in Korea was selected and investigated to design the three kinds of simulation algorithms for the shovel-truck haulage system of ores. GPSS/H simulation language was utilized to develop the simulation programs. The parameter values for simulations were collected by field investigations. The simulation results showed that 7 trucks are required for a real-time truck dispatch system with double shovels to maximize the profit of shovel-truck haulage system.

국문 초록 (Abstract)

본 논문에서는 트럭의 배차방식을 고려하여 노천광산 쇼밸-트럭 운반 시스템의 시뮬레이션을 수행한 사례연구 결과를 제시한다. 국내 석회석 노천광산 현장을 연구지역으로 선정하여 광석의 쇼밸-트럭 운반 시스템에 대해 조사하고, 연구지역에서 고정 트럭배차 방식과 실시간 트럭배차 방식을 고려할 수 있는 세 가지 종류의 시뮬레이션 알고리즘을 설계하였다. GPSS/H 시뮬레이션 언어를 이용하여 시뮬레이션 프로그램을 개발하였으며, 현장조사를 통해 시뮬레이션에 필요한 인자 값들을 결정하였다. 시뮬레이션 결과 두 대의 쇼밸로 적재작업을 수행할 경우 7대의 트럭을 실시간 트럭배차 방식으로 운영하는 것이 최대의 수익을 기대할 수 있는 것으로 나타났다.
