Mining design is part of the planning stages of mining as a very important factor is determined before the actual mining plan begins. CV. Kutai Kumala Energy is a company engaged in coal mining which has a Mining Business License located in Loa Kulu District, Kutai Kartanegara Regency, East Kalimantan Province. On CV. Kutai Kumala Energy pit BC was calculated with the aim of meeting the overburden of 5,095,565.38 BCM and the coal stripping target of 673,541.31 MT. In determining production targets for 1 year and in accordance with the capabilities of the tools at the research location.

Abstract

Composites are a combination of two or more different materials and their properties to form new materials that have better characteristics. The composite was previously composed of activated claystone, activated zeolite, and coconut shell activated charcoal with 3 ratios, namely: (claystone [C] : zeolite [Z] : activated charcoal [A] = 60:20:20; 20:20:60; and 20:60:20. This composite acts as an adsorbent in the adsorption process of acid mine water samples. Based on the results of the adsorption test, it was concluded that the composite cannot neutralize the pH of acid mine water. Of the three types of composites, Composite A (claystone [C] : zeolite [Z] : activated charcoal [A] = 60:20:20) showed a significant influence with a decrease in the concentration of heavy metals Iron and Manganese within 30 min of contact time. Fe adsorption capacity is 20,7 mg/g and Mn is 24,3 mg/g.

Abstract

Studi Keberhasilan Reklamasi merupakan kegiatan yang penting untuk mengukur perubahan lingkungan yang terjadi pada wilayah bekas tambang. Perubahan lingkungan yang dimaksud salah satunya adalah perubahan kimiawi yang berdampak pada air tanah dan air permukaan. Lebih jauh lagi adalah perubahan iklim disebabkan perubahan kecepatan angin, gangguan flora dan fauna, serta tanah menjadi tandus dan gundul. Menurut Kepmen 1827 K/30/MEM/2018, reklamasi adalah kegiatan yang dilakukan sepanjang tahapan Usaha Pertambangan untuk menata, memulihkan, dan memperbaiki kualitas lingkungan dan ekosistem agar dapat berfungsi kembali sesuai peruntukannya. Kegiatan pengamatan di lapangan dan hasil analisa seluruh tahapan kegiatan reklamasi, dapat dilakukan penilaian keberhasilan reklamasi PT. Tiwa Abadi. Penilaian tabel keberhasilan reklamasi ada 17 kategori dalam setiap penilaian tersebut menggunakan parameter poin yaitu 1,2, dan 3. Hasil poin penilaian mendapatkan rata rata yaitu 3 poin. Menentukan nilai akhir perhitungan yaitu Total Skor Evaluasi untuk masing-masing kriteria dibagi dengan Jumlah Kriteria dikali dengan Nilai Maksimal Tiap Kriteria kemudian dikali 100%. Nilai Pencapaian persentase keberhasilan reklamasi PT. Tiwa Abadi pada tahun 2023 yaitu 78,43%. Kegiatan reklamasi juga melakukan pengelolaan pH Asam Tanah pada PT. Tiwa Abadi dengan pH Tanah (5-6). Dari faktor penghambat keberhasilan reklamasi yaitu tidak tercapai luas area revegetasi, tidak melakukan penanaman (cover crop), pertumbuhan tanaman cepat tumbuh 50%, belum melakukan penanaman tanaman lokal, belum terlihat penutup tajuk, dan belum dilakukannya penyulaman pada area revegetasi.

Abstract

This study aims to measure the overburden volume at Pit 3HWE, PT. Indominco Mandiri using Unmanned Aerial Vehicle (UAV) technology. The use of UAV for volume measurement offers a more efficient and accurate alternative compared to conventional methods. In this research, aerial images were captured using a UAV and processed with photogrammetry software to generate a digital surface model (DSM) and 3D maps. The overburden volume calculations were analyzed and compared with manual measurement data as a reference. The results indicate that UAV usage provides accurate results with higher time efficiency, making it a viable method for mining operations. Factors affecting the measurement results, such as weather conditions and image resolution, were also analyzed in this study.

Abstract

The presence of a coal mining business permit not only has an economic impact but can also cause environmental problems. The objectives of this research are (1) to analyze the impact of PT XXX's overflowing voids on water management and water quality, and (2) to carry out spatial analysis, mapping and estimation of coal reserves that cannot be extracted by PT YYY. The research method is a case study selected by purposive sampling at two companies in North Kalimantan Province using water quality test analysis with grab sampling and estimating the potential loss of coal reserves using the rule of gradual changes and rule of nearest point methods as well as aerial photography. The research results show that in general the water use meets Class 3, namely: Water that can be used for cultivating freshwater fish, animal husbandry, water for irrigating crops, and/or other uses that require the same water quality as that use. Apart from that, PT XXX has built an overflow water channel into the PT YYY area without management approval, thus having a negative impact on PT YYY's mining plans which are dominated by peat land. Map of PT YYY's lost coal potential of 714,688 MT with an affected area of 15.16 hectares with details of 6.4 ha being the void area included in PT YYY's IUP area, 1.86 ha being the road and buffer zone area and 6.9 ha is a potential lost area of PT YYY.
