Evaluasi Geometri Jalan Tambang Di PT Vitrama Properti Desa Air Mesu Kabupaten Bangka Tengah
PT Vitrama Properti is a company engaged in mining sector that utilizes natural resources of granite. The condition of mine road at PT Vitrama Properti is not good, causing the lack of transportation productivity in the transportation process. This study aims to evaluate the geometry of the mine road. The method is terrestrial method. Data that obtained are data on straight road width, road width at bends, height differences and bend radius to evaluated with AASHTO. The smallest of road width is 4.67 m, the road width on the smallest bend is 5.8 m, the smallest height difference value is 0.9 m and the smallest radius of bend is 7.695 m. The evaluation results are the width of the haul road on a straight single lane minimum is 6.6 m, the width of the haul road on a straight two-lane minimum is 11.55 m, the width of haul road in two lines minimum bend is 16.485 m, the maximum slope of road is 10%, the superelevation is 4%, and the cross slope is 33 cm.
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
