Since the early 1990s, when the coal mining sector was reopened for foreign investment, Indonesia witnessed a robust increase in coal production, coal exports and domestic sales of coal. The latter, however, has always been rather insignificant as domestic consumption of coal is relatively small in Indonesia. But in recent years there has been a rapid increase in domestic coal sales because What are the types of coal mining methods? Quora,Commonly coal mining methods are divided into two kinds, open pit mining and underground mining. Open pit mining or surface mining method is used when coal seam position near the surface. While Underground mining is used when coal seam is far below the ground surface. On underground mining, instead of remove abundant overburden, it is more efficient makes tunnel to get coal.
