Abstract

Stockpile is a temporary storage place for coal before it is sold to consumers. The stockpile must be properly regulated so that the quality of the coal is maintained, so that when it reaches the consumer it is still of the desired quality. The plan is that in November the coal that will be included in the ROM stockpile of PT. Bara Mega Quantum will experience changes, both in quality and quantity. This study aims to determine the readiness of the stockpile to face the planned increase in coal production. PT. Bara Mega Quantum has a ROM Stockpile which is located southwest of the mining site, precisely located in the coal processing area on Pulau Baai Terminal Coal PT. Pelindo Bengkulu, Kampung Melayu District, Bengkulu City, Bengkulu Province. Where the distance between the pit and ROM Stockpile is approximately 67 km. The processing area consists of ROM Stockpile, Hopper, and Jetty Loading. Based on calculations from rainfall data, the total water discharge entering the ROM Stockpile area is 4393,67 m3/day. To accommodate this amount water, sufficient dimensions of the settling pond are needed to prevent overflow. Based on the data processing carried out, the dimensions available sludge settling pond are 5960 m3. The height of the coal pile is taken based on the specifications of the Whell Loader with the Komatsu 350 type. The following is a picture of the dimensions of the Whell Loader with the Komatsu 350 type used in the ROM Stockpile activity by PT BMQ. In accordance with the design that has been made and the data that has been processed for the capacity of the coal stockpile on the ROM Stockpile, namely on ROM 1, ROM 2 and ROM 3, the volume obtained is 20214.58 m3 and for tonnage 26278,95 MT.

Abstract

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.
