The mining industry sector plays a crucial role in the Indonesian economy. Indonesia has extensive mineral reserves and has become the world’s largest exporter of thermal coal. Indonesia produced about 257 million tons of coal in 2010 and is the second largest coal producer globally and the largest exporter of thermal coal. The distribution of coal resources in Indonesia is concentrated in the provinces of Kalimantan and Sumatera. As reported by the Ministry of Energy and Mineral Resourcesin November 2011, the total coal resources and coal reserves in Indonesiaare approximately 105,187 million tons and 21,131 million tons, respectively.
Coal mining is the operation of extracted coal from the ground. Coal mining processes are differentiated by whether they operate on the opencast or underground. Many coals extracted from both surface and underground mines require washing in a coal preparation plant.If the coal seam is fewer than 125 feet under the surface, it is mined by surface mining. Coal that is deeper than 125 feet is removed from the ground by underground mining.
In opencast mining operation of the coal seam, several benches are established in both the overburden strata and the coal seam. The surface mining is usually operated where thick coal seams are overlain by thick or thin overburden; it is also applied for mining steeply pitching coal seams. In the primary stages of mining operation, large volumes of overburden materials must be accumulated in large dump areas outside the mine. SBM provides complete range of coal opencast mining machine in Indonesia.
Coal surface mining is the operation of raw coal materials from the earth through their removal from an open pit or borrows. First coal will be extracted from the surface mines; the large block of raw materials will be transported to the crushing plant for primarily crushed. According to final products applications, it may be further crushed by fine crushing machine, and screened to separate the different size.
In coal surface mining operation, several types of machines will be applied, such as jaw crusher for primary crushing, impact crusher and cone crusher for further crushing. belt conveyer and vibrating screen will help separate the large particle and convey to further processing plant. Coal washing plant may be also applied.

The opencast coal quarry plant for sale in Indonesia includes jaw crusher, impact crusher, cone crusher, ball mill, high pressure mill, ultrafine mill, belt conveyor, screening machine, coal processing plant etc. We focus on substantial development on long term, and make effort in developing new technology.If you are interested, please contact us for more information.
Profits of the coal industry in Indonesia will be limited in the recent future. However, if we take the longer term into account - when global economic activity is recovery - demand from China and India is forecast to make the coal business very profitable again.
These promising future perspectives are the main reason that in recent years many Indonesian companies have started. Considering the rising energy prices and growing scarcity of energy sources, it will become more expensive to buy coal on the market in the future. For many Indonesian companies this is an incentive to start securing coal reserves now, and invest for high quality coal mining machine.
SBM designed the YKN series vibrating screen, which has high-strength exciting force.
PY cone crusher is applied widely in road building, construction industry for hard and mid-hard rocks and ores.
