Abstract

Coal mining in indonesia mostlyuses open pit mining methods. Including coal mines owned by PT Bima Nusa Internasional. Administratively, the research area is located in the muara komam area, batu sopang sub-district, paser district, east kalimantan. Open pit mining is a direct method that is exposed to free air above the surface. This study aims to determine the effect of rainfall on the production of coal hauling equipment at PT Bima Nusa Internasional. High rainfall can affect the performance of coal hauling equipment, which in turn has the potential to disrupt operational smoothness and reduce productivity. This study uses a quantitativeapporach by analyzing daily rainfall data for two months and coal hauling equipmentproduction data for a two months period. The results of the study show that there is a significant negative relationship between rainfall and the amount of coal transport equipment production.

Mitra Indah Lestari uses Hyundai 480 and Sany750-H excavators. The transport equipment used is Wechai WT90, Tonly TLD90, and Quester CWE 330. This study uses a quantitative method and obtains fuel consumption results, where the fuel consumption of the Hyundai 480 and Sany 750-H excavators is 37.89 liters/hour and 59.91 liters/hour, respectively. The fuel consumption of the Wechai WT90, Tonly TLD90, and Quester CWE 330 transport equipment is 25.19 liters/hour; 27.53 liters/hour; and 10.66 liters/hour, respectively.

Abstract

Mining roads play an important role in supporting the smooth running of mining activities, especially in the process of transporting materials. The bearing capacity of the soil as a road subgrade greatly affects the stability and resistance of the road to heavy equipment loads. This study aims to analyze the effect of the plasticity index and compaction parameters on the California Bearing Ratio (CBR) value, as well as to determine the thickness of the road layer based on the laboratory CBR value. Testing was carried out at the South Pit of PT. Bina Sarana Sukses site PT. Baramulti Suksessarana with a field test method using the Dynamic Cone Penetrometer (DCP) and laboratory tests such as proctor tests, Atterberg limit tests, and CBR tests on various variations of clay and sand soil mixtures. The results showed that increasing the plasticity index decreased the CBR value, while increasing the maximum dry density and decreasing the optimum water content increased the CBR value. Based on the laboratory CBR value, recommendations were obtained for the appropriate road layer thickness to ensure optimal bearing capacity for heavy equipment passing through the research area.

Abstract

The coal blending process conducted by PT. Bukit Baiduri Energi (PT. BBE) aims to achieve coal quality specifications that align with customer requirements. PT. BBE possesses multiple coal seams with varying quality characteristics, necessitating a carefully planned blending system with precise proportions to produce coal products that meet market demands. The objectives of this study are: to plan the quantity and quality parameters for coal blending, to evaluate the actual outcomes of coal blending in terms of quantity and quality, and to identify the factors contributing to discrepancies between the planned and actual coal quality following the blending process. To determine the optimal quantity and quality of each coal product in the blending plan, the simplex method was employed with the assistance of POM-QM for Windows version 5 software, alongside the weighting factor method. The final coal blending plan resulted in a total of 55,000 MT with the following quality specifications total moisture of 20.00% (ar), ash content of 6.10% (ad), total sulfur of 1.65% (ad), and a calorific value of 5,350 kcal/kg (ad). The actual blending outcome yielded the same quantity of 55,000 MT, with quality parameters as follows: total moisture of 20.18% (ad), ash content of 5.60% (ad), total sulfur of 1.35% (ad), and a calorific value of 5,340 kcal/kg (ad). The analysis of quality discrepancies revealed several contributing factors the presence of water accumulation in the ROM Stockpile following rainfall, which increased total moisture, the inadvertent inclusion of foreign materials into the feeder, resulting in elevated ash content, the unintentional mixing of coal from different product types, which led to inconsistencies in total moisture, ash content, total sulfur, and calorific value, and the rise in total moisture, which adversely affected the calorific value.

Abstract

Rock stability and service life in geotechnical and mining engineering are highly dependent on the rock's mechanical and physical parameters, where the variation in sandstone grain size is a crucial intrinsic factor. This study aims to comprehensively analyze the correlation between sandstone grain size with uniaxial compressive strength (UCS) and resistance to weathering (Slake Durability Index) in samples taken from the Balikpapan and Pulau Balang Formations in the Samarinda area, East Kalimantan. The research methodology involved a series of standard laboratory tests, including rock physical properties analysis, grain size distribution analysis, UCS testing, and slake durability testing through three cycles. The test results show a significant correlation: sandstone with finer grain sizes and higher density consistently demonstrates greater UCS values and a higher Durability Index, indicating superior mechanical and physical resistance. Specifically, the Pulau Balang Formation exhibits a more compact structure and finer grain size, resulting in better durability values compared to the Balikpapan Formation. These findings are important as a geomechanical data basis for slope design planning, rock mass stability analysis, and material selection in infrastructure projects or mining operations involving both formations.

Abstract

In mining activities, high risk is one of the main aspects that must be anticipated, especially regarding the geomechanical complexity of the rocks being excavated. Selecting the right excavation method can greatly impact operational efficiency and safety. In this context, direct digging, ripping, and blasting are the three main options, tailored to the characteristics of the rock.To determine the most suitable method, a rock rippability study is essential. This study can be conducted using direct or indirect methods. In this research, the seismic method was used to assess rock strength based on the seismic wave velocity, which was recorded at 1437.80 m/s. This value serves as a reference for selecting appropriate equipment for ripping activities.Given these characteristics, the recommended equipment for ripping is the D8T/D8R dozer from Caterpillar or the D275A/D275AX dozer from Komatsu. This equipment choice is based on its capability to handle rocks with strength levels reflected by the measured seismic wave velocity.
