Abstract

PT Mutiara Fortuna Raya's mining operations are currently guided by an annual mining design without detailed mining scheduling. However, variations in mining direction and sequence can lead to discrepancies in coal expose achievement, ultimately impacting coal production outcomes. High SR locations demand a more overburden volume and time. This research aims to evaluate various mining direction options to determine the most optimal approach. The research methodology uses a quantitative approach, comparing three mining scheduling scenarios: panel scenario, strip scenario, and block scenario. These scenarios are based on the 2023 reserve design results of 180,518 tons coal and 385,390 BCM of overburden. The outcomes of these three scenarios reveal varying stripping ratios across each period. Stripping ratio for the panel scenario: Quarter I SR 10.84, Quarter II SR 4.77, Quarter III SR 1.64, and Quarter IV SR 0.20. Stripping ratio for the strip scenario: Quarter I SR 5.11, Quarter II SR 2.40, Quarter III SR 1.67, and Quarter IV SR 0.53. Stripping ratio for the block scenario: Quarter I SR 8.93, Quarter II SR 3.10, Quarter III SR 1.74, and Quarter IV SR 0.21. Analysis of three scenarios indicates that block scenario presents the most favorable schedulling for implementation.

Potensi Logam Tanah Jarang (LTJ) pada Parting Batubara dan Estimasi Sumberdaya Hipotetik di PT Kuansing Inti Makmur: Potential of Rare Earth Elements in Coal Parting and Hypothetical Resource Estimation at PT Kuansing Inti Makmur Putri Abby Larassati; Muhammad Ikrar Lagowa; Yudi Arista Yulanda

Abstract

Rare Earth Elements (REEs) have become critical components in modern technology; however, global reliance on Chinese supply (>80%) and the scarcity of economic deposits necessitate the diversification of REE sources, including utilizing coal ash. This study examines the REE potential in coal parting as the primary source of coal combustion ash materials at PT Kuansing Inti Makmur (PT KIM), Bungo Regency, Jambi Province, which features multi-parting coal characteristics with a high ash content (14.36%). The methodology includes Inductively Coupled Plasma-Optical Emission Spectrometry (ICP-OES) analysis for REE quantification and petrographic analysis for mineralogical characterization. The results reveal that the total REE content in the parting reaches 180.01 ppm, dominated by Cerium (Ce) (65.68 ppm) and Neodymium (Nd) (38.91 ppm). Petrographic analysis identifies the REE-bearing host rock as siliciclastic sediment composed primarily of quartz and feldspar within a clay matrix. Based on a parting volume of 85,000 m3, the hypothetical resource estimation yields a total potential of 32.13 tonnes of REE, including Ce (11.7 tonnes) and Nd (6.9 tonnes). These findings indicate that the high-ash, multi-parting coal parting at PT KIM holds significant potential as an alternative REE source through the utilization of residual coal combustion ash. The presence of REE within the parting enables its accumulation and enrichment during the combustion process.
