摘要

PT Vitrama Properti是一家从事花岗岩自然资源开采的公司。PT Vitrama Properti矿路状况不佳，导致运输过程中运输生产力不足。本研究旨在评价矿山道路的几何形状。方法是地面方法。获得的数据包括直道宽度、弯道宽度、高度差和弯道半径等数据，以进行AASHTO评估。道路宽度最小值为4.67 m，最小弯道宽度为5.8 m，高差最小值为0.9 m，弯道半径最小值为7.695 m。评价结果为:单线直行运输道路宽度最小为6.6 m，双线直行运输道路宽度最小为11.55 m，双线运输道路弯道宽度最小为16.485 m，道路最大坡度为10%，超标高为4%，交叉坡度为33 cm。

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
