Abstract

Hauling road is an important aspect to support hauling activities in a mining operation. Better hauling road conditions will optimalize production, where is consistent with production plans and targets. The calculation of road conditions should be adjusted to the needs. The road geometry is a part of road planning which focuses on the physical condition of the road so that it can fulfill the road function. In addition to the geometry of the hauling roads, water can also affect the condition of the hauling roads. Therefore, it is important to conduct an evaluation of the hauling road conditions. Based on the calculation results, the straight road width is 8,575 meters, the hauling road width at the bend is 19,356 meters, while the straight road width in the field is about 7.6 meters and for curves in the field about 9 meters. From the field processed data, it is indicated that the existing hauling roads at PT Pro Intertech Indonesia mining operation has not fully met the hauling road requirements. Therefore, it is necessary to widen the hauling road in the operation area.

Abstract

Surface mine is a mining system where all the mining activities are carried out on the planet surface or on open air environment. In the open mining system there are several methods, one of which is the open pit/cut. PT. Ifishdeco is one of the mining companies engaged in nickel ore mining and applies open mining system with open pit/cut method. PT. Ifishdeco Block X pit design is carried out with the help of Surpac 6.5.1 software. The design process starts with estimating reserves using the Inverse Distance Weighting (IDW) method then using the company recommendation to design levels geometry with bench dimension of 5 m high, 6 m width, 45o slope, overall slope of ≤ 25 0, catch bench width of 1 m and mine road width 8 m with 8% slopes. Furthermore, proceed with designing a pushback or progress of the mine based on the elevation with 5 months mining operation plan.
