<![CDATA[This study aims to conduct an in-depth study and evaluation of the geometry of the haul roads used by dump trucks from the Front Pit I mining area to the Disposal Area in the operational area of PT Long Daliq Primacoal. The background of this study is the understanding that haul roads are the lifeblood of mining activities whose efficiency greatly determines productivity. Haul road geometry that does not comply with technical and safety standards can trigger various serious operational risks. These problems can not only cause fatal accidents that endanger operators, but also result in premature damage to vital equipment components such as tires and suspension, and cause a decrease in overburden transport efficiency due to slow cycle times and increased fuel consumption. In this study, the methodology applied was a direct survey in the field to collect actual data. The data was then processed through quantitative analysis to assess key parameters of the road geometry, including road width on straight and curved segments, slope level (grade), and curve radius. The results of the study indicate that the existing condition at PT Long Daliq Primacoal has several significant deficiencies, such as several road segments whose width is inadequate for two-way traffic and slope levels that exceed safe limits. Based on these findings, several technical improvements, such as road widening and slope smoothing, are recommended to increase safety factors and optimize overburden transport efficiency in a sustainable manner.]]>
