This paper describes the condition of underground coal mines and mining technology in Indonesia firstly, and then discusses the subsidence behavior due to the longwall mining operation based on the measured data in Balikpapan coal-bearing formation in Indonesia.
Coal is extracted from the ground by coal mining, either underground by shaft mining, or at ground level by open pit mining extraction. In 2010 the largest exporters were Australia with 328 million tonnes (27.1% of world coal export) and Indonesia with 316 millions tonnes (26.1%), 207 million tonnes (17.5% of world coal import), China with

coal mining regulation and coal demand will significantly impact the availability of Indonesian coal on the export market, with a possible major spillover effect on international coal prices. Despite being Southeast Asia’s largest energy producer and consumer, Indonesia remains an energy-
Jan 25, 2016· China: Most coal mining in China uses the underground longwall mining technique. It was reported in 2009 that China intended to establish eight to ten large mines with an output of "around 50 Mt" each in the states of Shanxi, Shaanxi, Inner Mongolia, and Ningxia.
To meet the demand for coal in Indonesia and the rest of the world, underground mines have to be developed in the near future. Under these circumstances, the development of underground coal mines from the toe of open-cut highwalls is being planned in several mines in Indonesia. However, if the conventional mining systems and designs
For the third consecutive month Indonesia's benchmark coal price declined. This price (in Indonesian: Harga Batubara Acuan, or HBA), which is based on a selection of domestic and international coal indices, is set on a monthly basis by Indonesia's Energy and Mineral Resources Ministry.
