Evaluasi Kemiringan Jalan Tambang Terhadap Cycle Time Alat Angkut Pada Dump Truck Hino FG 235 JJ Tambang Batu Granit Di PT Aditya Buana Inter Kabupaten Bangka
PT ABI is a private company engaged in the granite mining business using the open pit method. The problem encountered is that there is a slope of the mine road that does not comply with the standards set by the company, namely ≤ 8%, the slope of the mine road, which is not suitable, makes the truck to produce large rimpull, which affects the overall distribution time. This study aims to evaluate and optimize the dump truck cycle time obtained. This research begins by calculating the actual travel time on 2 dump trucks in 40 trips, conveyance A gets 493.72 seconds and conveyance B is 495.75 seconds, the actual travel time on the haul road segment exceeds ≥ 8%, i.e. in the B-C segment which has a grade of 8.86% with an average travel time of 20.38 seconds and in the C-D segment which has a grade of 10.51% with an average travel time of 37.91 seconds. Obtained circulation time decreased by 5 seconds from 494.73 seconds to 489.69 seconds with a percentage increase of 1.04% after optimization, meaning that the conveyance can transport 89 tons more of material.
期刊介绍：
Mineral Economics – Raw Materials Report is an international multidisciplinary journal focused on economics and policy issues in the minerals metals and mining industries. The journal exists to improve the understanding of economic social environmental and political implications of natural resources. The main focus is on non-fuel minerals metals and the mining industry and its role in society.Mineral Economics is widening its scope and particularly invites papers on: Socio-economic aspects of mining e.g. social license to operate indigenous peoples theory of change Materials for the Green transition e.g. battery metals ICT elements policies to secure supply of these elements Minerals in the periphery e.g. the Arctic deep-seabed and space Mineral Economics serves as a platform for academics industry practitioners decision makers and other experts who want to share perspectives and knowledge about natural resources.A wide range of topics have traditionally been covered including among others: mineral market analysis exploration and development resource availability market development price formation international trade environmental policy sustainability issues competition issues.Mineral Economics is a joint project of Lule? University of Technology and R?varugruppen Ekonomisk F?rening the organization which founded the journal Raw Materials Report in 1981
