JAKARTA - Special Staff to the Minister of Energy and Mineral Resources (ESDM) for the Acceleration of the Minerba Governance Division of the Ministry of Energy and Mineral Resources, Irwandy Arif, projects that there will be more underground mining trends in the future considering the fewer reserves near the surface.

Although it costs higher in mining activities, it has a smaller risk of damage compared to surface mines.

"There will be more and more underground mining trends in the future considering the fewer reserves near the surface. Although there are challenges in the form of relatively large investment costs, increasingly sophisticated technology and the availability of human resources but have opportunities to reduce the risk of environmental impacts where environmental impacts appear smaller than surface mines," said Irwandy in his statement to the media, Saturday, December 23.

He added that the cost of underground mining operations was higher due to additional costs for ventilation, buffer, and so on. The cost of underground mining operations is approximately twice as expensive as open mines. The cost of underground mining capital/capital mining is approximately 3-4 times more expensive than open mines.

"The cost of underground mining is indeed greater than open mining, but with the disruption technology, some costs can be cut openly," continued Irwandy.

Irwandy mengungkapkan, peluang dan masa depan tambang bawah di Indonesia akan semakin meningkat karena berbagai hal antara lain semakin penurunan deposit (cebakan) berkadar tinggi pada atau dekat daerah untuk dipambang Dengan lain, meningkatnya kedalaman deposit akan menyulitkan bila ditambang dengan sistem tambang terbuka karena terbatas oleh Stripping Ratio dan ditemukan teknologi baru dalam peralatan Tambang Bawah Tanah.

"Tightening and restrictions on environmental issues, as well as reduced mobility of mechanical equipment in open mines if mining deepens into the next reason," added Irwandy.

The potential for underground coal mining in Indonesia is still very large, for example at Barito & Asam-Asam Basins with 6 Blocks with potential in it with a total potential of 530,711 MTon in Kutai and Tarakan Basins from 13 Blocks. there is a potential of 12,344,515 MTon and in South Sumatra Basins from 20 Blocks there is a total potential of 20,658,330 MTon Coal.

Currently, apart from PT. Energy Resources (SDE) which have just inaugurated the first production of underground mines, there are 15 other underground coal mining companies in Indonesia, including CV Gold Water and PT Nusa Alam Lestari in West Sumatra, PT Merge Mining Industri South Kalimantan, PT Kusuma Raya Utama in Bengkulu, PT Gerbang Daya Mandiri East Kalimantan, PT Energy Resources, PT Vipranity Power Energy, PT Sugico Pendragon Energi and PT Indonesia Multi Energi in South Kalimantan.
