Some of the concerns related to hydrological issues include the drainage system and its design preparation. In special cases where river diversion is required, there may be specific issues with the planning and construction process. In such instances, a diversion channel is planned to be built between two closely situated pits. This channel will be constructed upon an embankment consisting of disposal materials. The plan has implications for the spatial positioning and the choice of materials for the channel base. The embankment requires proper treatment and processes during its construction, such as compaction and consolidation. This study addresses the effectiveness of compaction efforts on the material's capacity concerning its physical, mechanical, and hydrogeological properties. The analysis was conducted using correlations between laboratory test results and extracted hydrogeological data using software instrumentation. These correlations specifically examine the changes in compaction values in relation to changes in material properties. The study concludes that compaction efforts have a significant impact on the material's ability to support the diversion channel, making it an effective means of enhancing the material's capabilities2023-10-31T04:18:39+00:00Copyright (c) 2023 Mining Technology Journalhttp://jurnal.upnyk.ac.id/index.php/mtj/article/view/11071Phytoremediation Agent of Mercury Waste on Indonesian Small-Scale Gold Mine Using Hyacinth2023-10-31T03:46:49+00:00Andika S Saputra116200024@student.upnyk.ac.idDiva Kanigara116200024@student.upnyk.ac.idShofa Rijalul Haqshofa.haq@upnyk.ac.idAmalgamation is the common method to process and purified gold in a tube in small-scale mine worldwide, especially in Indonesia. The method uses mercury (Hg) to bind gold metals, which pollutes the environment. Therefore, this reviewed paper aims (i) to assess the environmental impact of small-scale gold mine in Indonesia and (ii) to evaluate the used hyacinth to ameliorate the deterioration on surface water quality. Hyacinths potentially reduce Hg levels in gold mining wastewater. Hyacinths are proved to absorb heavy metal in mercurial wastewater of gold mining. The addition of 500 gr/L hyacinth to mercurial wastewater would decrease 79.7% of Hg concentration. The more hyacinths, the more Hg levels will be absorbed.2023-10-31T04:18:39+00:00Copyright (c) 2023 Mining Technology Journalhttp://jurnal.upnyk.ac.id/index.php/mtj/article/view/11072Study on Digging and Loading Equipment Requirement for the Reclamation Plan in the Coal Mining Area of PT. Timah in Paku Village, Payung District, South Bangka Regency, Province of Bangka Belitung Islands2023-10-31T03:47:39+00:00Kristanto Jiwo Saputrokristanto.jiwosaputro@upnyk.ac.idSheny Linggasarishenny.linggasari@upnyk.ac.idOktarian Wisnu Lusantonooktarian.lusantono@upnyk.ac.idReclamation activity is one of the activities carried out in mining planning. This reclamation activity needs to be well planned. One of the reclamation activities is land arrangement. This land arrangement activity can be carried out by backfilling in ex-mining holes. This back filling activity is carried out by PT. Timah in carrying out reclamations related to land management. Former mining pit at PT. Timah will be back-filled in 2026 or the third year in the life of the mine. The back filling that will be carried out starts from RL 10 to RL 59. RL 59 is the target because the altitude is the same as the surrounding conditions. To carry out back filling on the plan, a material volume of 2,623,400 m3 is required. The age of the mine is only until 2029, so with the material requirements divided by 4 years of reclamation, 655,850 m3 per year is obtained. The equipment used to meet annual needs is 1 Dozer Komatsu D85 A, 1 Excavator CAT 320 D, and 5 dump trucks Scania P410.2023-10-31T04:18:39+00:00Copyright (c) 2023 Mining Technology Journalhttp://jurnal.upnyk.ac.id/index.php/mtj/article/view/11073Review On The Effect Of Vegetation On Waste Treatment In Mining Wetlands2023-10-31T03:49:24+00:00Laurencius Pieteurslpieteurs@gmail.comAkbar Ivansyahlpieteurs@gmail.comAndrejassi Pegasoln Damaniklpieteurs@gmail.comShofa Rijalul Haqshofa.haq@upnyk.ac.idFaizal Agung Riyadifaizal.agung@upnyk.ac.idThis study discusses the influence of vegetation growth on waste treatment in mining wetlands. Mining wetlands are wastewater treatment systems that use plants as treatment agents. The aim of this research is to provide information on the impact of vegetation growth in mining wetlands on the effectiveness of waste treatment. The method used is a literature review by searching for articles and scientific journals related to the influence of vegetation growth in mining wetlands. The research results indicate that vegetation growth in mining wetlands has a positive effect on the effectiveness of waste treatment. The more plant species that grow, the better the waste treatment. The pH and TSS levels of the water in the wetlands also increase with the presence of vegetation. Moreover, the levels of Fe, Mn, Pb, and decreased with the presence of vegetation. Additionally, the vegetation with the best productivity while maintaining its condition is Typha sp. This plant can also survive in wetland areas with high water levels. In conclusion, the presence of vegetation has a positive impact on waste treatment in mining wetlands and can be an effective solution to address water pollution in mining areas.2023-10-31T04:18:39+00:00Copyright (c) 2023 Mining Technology Journalhttp://jurnal.upnyk.ac.id/index.php/mtj/article/view/11074Utilization of Reject coal from hauling activities as fertilizer: Coal handling strategies2023-10-31T03:52:48+00:00Roy Nastigor Nasutionmountforest249@gmail.comEdy Nursantoedynursanto@upnyk.ac.idRika Ernawatirika.ernawati@upnyk.ac.idManagement of rejected coal in the coal mining industry has become a major concern in efforts to reduce waste and manage resources more sustainably. One approach that has been proposed is the use of rejected coal as an agricultural fertilizer, with the aim of reducing the amount of rejected coal that must be transported and disposed of in active disposal. The research aims to analyze the effect of using reject coal as a fertilizer on the transportation of rejected coal to active disposal. This research will examine the impact of using reject coal as fertilizer on the volume and frequency of transporting rejected coal to active disposal.2023-10-31T04:18:39+00:00Copyright (c) 2023 Mining Technology Journal
