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.

PT Ifishdeco is a mining company that uses backhoe Sany SY-365 in its demolition activities. One of backhoes used has the greatest mechanical avaibility compared to others, so it is necessary to analyze the replacement of equipment in order to know the right time for replacement. The method used is the engineering economic method of Net Annual Value (NAV) with the concept of ‘defender’ and ‘challenger’ to analyze the cost and benefits of the equipment that can be distributed anually. To determine the NAV of an equipment and to know the the right time for replacement, it is necessary to know how much revenue and cost required for the backhoe to operate during the replacement of the old backhoe (defender) with a new backhoe (challenger) by conducting a replacement experiment in the first year after the tool operates until the end of the project life. The calculation results indicated that the replacement of equipment is more profitable at the sixth year of the project time, with NPV value of USD 29,530,448.96 and NAV value of USD 4,012,241.81.
