Abstract

Artisanal gold mining in the Kahayan River Basin (DAS Kahayan), Ramang Village, produces tailings that contain metallic minerals such as zircon (Zr), yet their management remains suboptimal. This study aims to identify the zircon content in the concentrate resulting from shaking table separation and to analyze the geological and hydrological factors influencing its distribution. The results show that zircon content in the tailings ranges from 0,002% to 0,112%. The highest concentration was found in the upstream area (Z1), while the lowest was in the downstream area (X1), indicating that river flow direction and tidal influences play a role in zircon particle distribution. The zircon identified is genetically linked to the weathering of granite rocks, particularly the Kapur Granite Formation and Sepauk Tonalite in the upstream region. These findings indicate that current small-scale gold mining practices remain inefficient, allowing zircon to be discarded in tailings. This study emphasizes the importance of improved tailings management through efficient containment systems, the potential for reprocessing, and continuous environmental monitoring to enhance resource utilization and reduce the ecological impact of traditional mining.

Abstract

This research aims to make a technical design for mining in Pit B, an area planned by PT Indo Muro Kencana to be exploited based on the evaluation of economic ore reserves. Pit B is an area that has never experienced mining activities before. The mine design method involves a technical design process that considers geotechnical, topography, and reserve data aspects to determine an economical and technically feasible mining deadline. The purpose of this method is to produce an optimal and safe mining design, in order to maximize the extraction of mineral reserves by paying attention to work safety. The research method applied is quantitative, used to design pit and waste dump designs and calculate the difference in reserves between the researcher's design results and the company's pitshell data using surpac software. Descriptive analysis is carried out to explain the design process and calculation of the proposal. The pit geometry parameters include a level height of 15 meters, a level width of 5 meters, a slope of 60°, and a ramp width of 15 meters with a slope of 10%, according to the company's operational standards. The results of the calculation of the reserve volume showed that ore amounted to 326,809 tons and waste 4,911,173 tons. The reserve difference between the design and pitshell data is still within the company's tolerance limit of 33%, so this technical design is suitable as the basis for mining operations in the field.

Abstract

The Banturung region mostly consists of the morphology of igneous rock hills where most of the rocks physically show that they have undergone a process of change, so more detailed research is needed to distinguish the types of rocks that exist at the research site. This study aims to determine the distribution and types of rocks that undergo alterations at the research site. The research method with petrographic analysis, due to mineral changes and changes in rock composition in alterations can be observed from microscopic observations by paying attention to the mineral composition. The rock sample is cut into thin incisions measuring 0.035 mm so that it can be observed under a microscope. From the results of the rock incision analysis, it is known that the characteristics of rock alteration at the study site include the type of Phyllic alteration with serisite as a key mineral, with a very low alteration intensity < 25%, and hydrothermal alteration processes in dacite and tonalite rocks. This alteration process can be an early indication of the formation of metallic minerals or mineralization of valuable minerals at the research site, which is also strengthened by the discovery of pyrite minerals at the research site so that it can be further developed as a source of mineral resource research.

Abstract

Mining sequence design is one of the important stages in open pit mining activities that aims to organize the excavation stages so that production activities run effectively, efficiently, and in accordance with the established targets. This research was conducted at PT Putra Perkasa Abadi Site SKS with the aim of designing a mining sequence in January and February 2025. The methods used include analysis of topographic data, geology, pit design, and monthly production targets. The data was processed using mining software to determine the excavation sequence based on elevation, overburden volume, and coal reserves. The design results show that the total planned overburden and coal volume is able to meet the company's production targets by considering slope stability and the efficiency of digging and loading equipment. In addition, the resulting sequence design also takes into account aspects of work safety and field operational conditions, such as mine road access and drainage systems. With a structured design, it is expected that mining activities during this period can run according to schedule, minimize operational obstacles, and support the achievement of production targets and cost efficiency at PT Putra Perkasa Abadi Site SKS.

Abstract

PT. Barito Bangun Nusantara is a company engaged in coal exploration and production activities, where the production is temporarily stored in a stockpile area before being processed or distributed. Stockpile management requires attention to several important factors, such as area design and stockpiling methods, so that storage runs effectively and does not cause a decrease in coal quality. This study was conducted on old and new stockpiles with the aim of analyzing the actual stockpiling conditions and providing technical recommendations regarding the ideal stockpile capacity and configuration. The research methods included field observation, primary and secondary data collection, and descriptive quantitative analysis. The results showed that both stockpiles experienced inefficiencies due to excess capacity. The actual tonnage reached 49,191.98 tons, exceeding the planned capacity of 35,000 tons, with a stockpile height reaching 9 m. This condition caused long stacking times and the FIFO system did not operate optimally. The study recommended an ideal stockpile capacity of 30,740.61 tons, with a maximum height of 8 m. The recommended angle of repose for the old stockpile is 30°, with a capacity of 11,542.19 tons, while for the new stockpile, it's 34°, with a capacity of 19,198.42 tons. This arrangement is expected to allow for a smoother unloading process and a more ideal stockpile.

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

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.
