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 belo
Most of coal mines in Indonesia are open pit mining method which disturbs large area of land. One of open pit mining impact is damage land and related to soil erosion occurrences it will degrade land by top soil loses.
