Abstract
This study presents a novel methodology to determine the optimal haulage routes of dump trucks in large-scale open pit mines. The proposed methodology for optimal haulage routing considers multiple criteria which can significantly influence the planning of truck haulage routes. The discrete friction cost which represents adverse affects of truck movement can be assigned using a fuzzy membership function and the weight of each criterion can be determined through the Saaty’s pairwise comparisons. The application at the Roto South in the Pasir open-pit coal mine, Indonesia showed that the proposed methodology could make optimal solutions to determine the haulage routes of waste dump trucks between loading locations and waste dumps and could approximately estimate the truck travel time along the optimal haulage route.
본 연구에서는 대규모 노천광산의 운반 효율성 개선을 위해 활용할 수 있는 덤프트럭의 최적 운반경로 분석 모델을 개발하였다. 개발된 분석 모델은 운반거리, 지형경사, 수계 및 광체와의 접근성, 운반로 유지관리 작업의 용이성 등 노천광산 현장의 다양한 영향요인들을 복합적으로 고려할 수 있다. 또한, 퍼지 맴버십 함수의 정의와 쌍대비교 기법의 적용을 통해 영향요인들의 저항비용과 가중치를 합리적으로 산정할 수 있다. 인도네시아 파시르 석탄 노천광의 로또 강남지역에 대하여 개발된 분석 모델을 적용한 결과 현장의 작업계획을 반영한 폐석운반 덤프트럭의 최적 이동경로를 분석할 수 있었으며, 운반작업에 소요되는 덤프트럭의 이동시간도 근사적으로 예측할 수 있었다. 본 연구에서 개발한 분석 모델은 작업계획에 따라 덤프트럭의 최적 운반경로를 신속하게 제시할 수 있으므로, 대규모 노천광산의 운반 시스템 효율성 개선에 크게 기여할 수 있을 것으로 기대한다.
