This study discusses blasting activities, which are a crucial stage in hard rock mining, because they are effective in demolition but also pose high risks to the safety of workers, equipment, and the environment. This study evaluates blasting site assessments as risk control indicators in two mining areas of PT Bukit Asam Tbk, namely the Suban Jeriji Selatan (SJS) Pit and Banko Tengah Block A (BTA) in Tanjung Enim, South Sumatra. The method used is a qualitative approach through direct field observation, including the use of assessment forms and data collection of blasting equipment. The evaluation is carried out using a scoring system, where the maximum total score is 300 points indicating safe conditions if achieved. The results show that in the SJS Pit, 7 locations were evaluated and 35% of them managed to obtain scores above 270 points, indicating that the area is overall safe for blasting activities. This study also refers to the Decree of the Minister of Energy and Mineral Resources Number 1827 K / 30 / MEM / 2018 concerning Good Mining Engineering Principles, as a reference for implementing safety standards in blasting activities.

This study aims to conduct a comprehensive evaluation of the key components and effectiveness of blasting activities in the PT Bukit Asam mining area, specifically in Pit 2 Banko Barat. The main objective is to quantitatively determine the distribution of blasted rock fragmentation, as this is a critical factor that affects the productivity of the entire mining operation cycle, from ease of digging to crusher efficiency. To achieve this objective, this study applies a systematic methodology, beginning with field observations to directly observe each stage of the blasting process, from blasthole preparation to post-blast testing. Primary data collection includes blasting geometry parameters (burden and spacing), the types of explosives used such as ANFO and Powergel, and visual documentation of the pile of blasted material (muckpile). This data is complemented by secondary data in the form of geological conditions of the area. The culmination of the analysis was carried out using Split Desktop software, which analyzes digital images of the muckpile to generate fragmentation distribution curves. The results show that the pattern and explosives used have been adjusted to field conditions, where their effectiveness is validated through measured fragmentation data that serves as the basis for further blasting optimization.

This study aims to conduct an in-depth evaluation of the current firefighting techniques at PT Budi Gema Gempita. To achieve this objective, a combined research method was used, including field observations to observe stockpiling and handling practices, periodic temperature measurements using an industrial thermogun to detect hot spots, interviews with operators to understand standard procedures, and secondary data analysis. The results identified that the main triggering factors for firefighting at the site were a combination of internal coal characteristics, namely high levels of Total Moisture (31.36%) and volatile matter (40.45%), which were exacerbated by storage periods exceeding two months. Field temperature measurements successfully detected a critical point in Seam 6 with a temperature reaching 72°C, indicating an advanced oxidation process that requires immediate treatment. This study evaluated two treatment methods: the use of an excavator alone and a combination of an excavator and chemical solutions. Conventional treatment, which involved dismantling and cooling the pile using an excavator, proved to be quite effective for heat dissipation. However, the combination method of spraying chemical liquid after dismantling shows far superior results, as it is able to reduce the temperature drastically and more quickly while stopping the oxidation process by coating the coal surface, thus offering a more efficient and complete solution.

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.

PT Bumi Merapi Energi (BME) faces challenges in optimizing the use of industrial diesel fuel for its transport fleet, which is crucial for operational cost efficiency. The company relies on 30-ton class dump trucks to transport coal, so planning fuel consumption in line with production targets is a top priority. This research was conducted at the Kungkilan Block mining site of PT BME, which is administratively located in Muara Maung Village, West Merapi District, Lahat Regency, South Sumatra. The coal loading process in the pit area uses a loading tool in the form of a Hyundai K40 excavator. The effectiveness of this operational activity is greatly influenced by various factors, including dynamic work area conditions, the applied loading methods and patterns, and the cycle time of the loading equipment. Analysis of these factors is important to understand the productivity of the equipment and the required fuel consumption. This study calculates the total actual fuel consumption of the Renault K40 dump truck unit. Based on operational data during day and night shifts, it was found that the total diesel fuel consumption for one unit reached 134,910,650 in relevant units (e.g., Rupiah or liters, depending on the original context of the study), which highlights the large energy costs in the production cycle.
