Abstract

This study was conducted to evaluate the level of conformity between actual mining activities in March 2025 and the monthly sequence design plan at PT Tama Raya's P3000BK14 pit. The evaluation focused on geometric deviations, volume achievement, and changes in field conditions that influenced these discrepancies. The data used included the sequence design, actual topography from the TLS (Low-Scale Land Survey), and weekly production realizations. The results showed significant discrepancies between the planned and actual operations in weeks 2 and 4, primarily in the form of overcuts, undercuts, non-designed contour changes, thinning of the coal seam, and hydrological obstacles such as ponding and unstable drainage. The R2 sequence redesign in week 4 proved to improve the overburden excavation flow but did not fully restore coal access due to persistent geological and water conditions. These findings emphasize the need for more rapid topographic updates, more intensive water handling, and interdepartmental coordination to ensure better synchronization of plans and operations.

Abstract

This study was conducted at PT Satria Alam Manunggal Site TOP to analyze the effect of road geometry conditions on the performance of Scania P410-B6x4 transport equipment in overburden material transportation activities. The haul route from the front to the disposal site is 2.4 km long, with an average hauler productivity of 33 BCM/hour, while the company's target is set at 40 BCM/hour. This situation indicates an issue with the hauler's travel time when transporting overburden material from the front to the disposal site, resulting in the hauler's productivity not being achieved. The analysis was conducted by dividing the haul road into 29 segments, consisting of 27 straight segments and 7 curved segments. The minimum width of straight roads is 9.1 meters for two lanes and 5.2 meters for one lane, while for curves, the minimum width is 16.29 meters and 9.31 meters, with a maximum road gradient (grade) of 8%, as well as other elements such as curve radius, superelevation, cross slope, safety berm, and drainage channels, also affect operational comfort and safety. The objective of this study is to evaluate and provide recommendations for road geometry improvements to meet technical standards, thereby reducing travel time and increasing transportation vehicle productivity.

Abstract

Blasting in open pit mines aims not only to achieve optimal rock fragmentation but also to control the impact of generated ground vibration. This study aims to analyze the influence of the crush zone on Peak Particle Velocity (PPV) in blasting activities involving claystone and limestone layers. Field data were collected from 25 blasting operations with varied parameters: number of blast holes 25–160, explosive charge per hole 50–111 kg, and measurement distance 504–537 m. The recorded actual PPV ranged from 1.221 to 3.404 mm/s. Statistical analysis was performed using power regression to model the relationship between Scaled Distance and PPV. The results show a strong inverse relationship between Scaled Distance and PPV, where higher blasting energy concentration forms a more intensive crush zone as the initial source of vibration. Blasting in limestone yields relatively higher PPV compared to claystone under similar Scaled Distance conditions, due to the elastic and more brittle properties of limestone. The model's prediction accuracy reached 91.5% on average. Practically, to maintain PPV at a safe level (<3.404 mm/s), it is recommended to keep the Scaled Distance ≥ 48.82 m/kg⁰·⁵ and limit the explosive charge per hole to the range of 50–90 kg, especially in limestone. This study confirms the key role of the crush zone and rock lithology in blasting vibration mechanisms, providing a basis for optimizing safe and sustainable blasting designs.

Abstract

Sand mining activities at Km. 29 in Bukit Batu District, Palangka Raya City, have caused significant physical land damage. This study quantifies erosion rates in former sand mining areas using the Universal Soil Loss Equation (USLE) through field surveys and laboratory analysis. Soil samples were collected purposively from four locations (Kolong 1 TL, Kolong 2 TL, Kolong 1 BD, Kolong 2 BD) at 0-20 cm depth with three replications. Results showed erosion rates ranging from 0.54 to 2.52 tons/ha/year, classified as “very low” according to standard erosion hazard categories. However, in post-mining contexts with initial degradation, these rates indicate serious land vulnerability. The dominant factors influencing erosion were high rainfall erosivity (R=998.45 MJ.mm/ha/hr/year), minimal vegetation cover (C=0.8), and the absence of conservation practices (P=1), whereas soil erodibility was inherently very low (K=0.005-0.014). Although numerically classified as very low, the former sand mining land requires immediate conservation intervention. Practical implications emphasize integrated conservation through vegetative approaches (fast-growing cover crops) and mechanical methods (gulud terraces and rorak), focusing on modifying the conservation practice factor (P) as the most easily intervenable variable to prevent increased erosion and restore land conditions.

Abstract

Land reclamation is a crucial effort to restore former mining land so that it can function ecologically and economically again. XYZ conducts reclamation activities to meet applicable regulatory standards, therefore an internal assessment is required first before reporting to the ministry. This study aims to analyze the achievements of land management activities at the reclamation stage in PT. XYZ. The research method used is quantitative descriptive, with data collected through field observation and document analysis. The results of the study show that PT. XYZ has reached 25% of the reclamation plan in the first phase, with land management activities running for ±2 months. However, this study also identified obstacles such as less fertile soil conditions and high rainfall, as well as the absence of erosion and water control buildings made by the company, even though they are included in the reclamation activity plan. One of the settlement options that need to be done to achieve optimal reclamation success is to increase tools and working hours at the reclamation activity site, considering that the success of reclamation is the basis for company reporting and the ministry's assessment of the sustainability of the company's activities.

Abstract

Produktivitas alat gali muat dan angkut merupakan faktor utama penentu keberhasilan operasi tambang batubara, namun sering terhambat oleh faktor eksternal seperti cuaca dan kualitas jalan. Penelitian di Pit SM-A PT XYZ, Kalimantan Timur ini menganalisis pengaruh curah hujan dan variasi kondisi jalan terhadap kinerja excavator dan dump truck. Dengan menggunakan data sekunder, dilakukan analisis sensitivitas untuk membandingkan kinerja alat pada kondisi cuaca cerah dan hujan, serta pada jalan kering, berdebu, licin, dan berlumpur. Simulasi produktivitas juga dilakukan dengan memvariasikan cycle time dan efisiensi kerja sesuai skenario tersebut. Hasil penelitian menunjukkan bahwa peningkatan curah hujan memperpanjang cycle time dump truck hingga 15,6% dan menurunkan efisiensi kerja excavator hingga 12,7%. Dampaknya, produktivitas excavator menurun sebesar 5,0-16,5% dan dump truck menurun sebesar 2,8- 13,1%. Kondisi jalan basah dan berlumpur menjadi faktor dominan penurunan kinerja karena memperlambat kecepatan angkut dan memperpanjang waktu siklus. Simulasi menegaskan bahwa produktivitas maksimal dicapai pada cuaca cerah dengan jalan kering, sedangkan hujan lebat dengan jalan berlumpur menciptakan kondisi paling kritis. Oleh karena itu, pengelolaan jalan angkut yang baik serta strategi operasi yang adaptif terhadap cuaca sangat diperlukan untuk menjaga efisiensi dan keberlanjutan operasi penambangan. Kata kunci: Alat angkut, curah hujan, cycle time, kondisi jalan angkut, produktivitas

Abstract

This study is motivated by the discrepancy between production targets and actual field performance caused by dynamic operational conditions, such as equipment productivity and effective working time. The objective of this research is to redesign the production target and develop a more realistic mine sequence using a rolling plan approach at Pit Hill16. The method includes analyzing the productivity of loading and hauling equipment based on cycle time data, calculating effective working time, and determining production targets using the rolling plan method. Furthermore, mine sequence design is developed based on the adjusted production targets. The results indicate that the productivity of loading equipment is 241.98 BCM/hour for the EC480DL excavator and 123.27 BCM/hour for the EC210DL excavator, while hauling equipment productivity is 40.24 BCM/hour. The April production target based on the rolling plan is 275,913 BCM, which can be achieved through mine sequence design with a volume of 277,839 BCM, resulting in a difference of +1,926 BCM, still within acceptable planning tolerance. Therefore, the rolling plan approach is proven to produce a more adaptive and realistic mining plan under actual field conditions.

Abstract

Blasting is a critical method for overburden removal in open-pit coal mines, where fragmentation quality directly impacts loading efficiency and operational costs. This study aims to analyze the actual fragmentation resulting from overburden blasting at Pit 4 Middle of PT. Victor Dua Tiga Mega, Central Kalimantan, to predict fragmentation using the Kuz-Ram model, and to evaluate the conformity of both results against the company standard (boulder size ≤144.6 cm or ≥50 cm for analysis). The research employed a quantitative comparative method. Primary data included blasting geometry and photographs of muck piles from 10 blasting events, which were analyzed using WipFrag software to obtain actual fragmentation distribution. Secondary data comprised rock characteristics and explosive properties for Kuz-Ram prediction input. The results showed significant variation in actual boulder percentage (≥50 cm), ranging from 6.19% to 32.91% with an average of 16.05% (medium category). Statistical analysis revealed a very weak negative correlation (r = -0.21) between powder factor (PF) and boulder percentage, indicating that PF is not the dominant factor within the consistent application range (0.21-0.23 kg/bcm). Comparison with Kuz-Ram predictions showed that the model consistently over-predicted coarse material, with an average difference of +25.21%, suggesting the need for rock factor (A) recalibration. It is concluded that the blasting results are inconsistent, strongly influenced by uncontrollable factors such as geological conditions. Recommendations include geometri evaluation, particularly burden and spacing, and calibration of the Kuz-Ram model for more accurate future predictions.
