Coal mining
Open-pit mining. In open-pit mining of the coal seam, several benches are established in both the overburden strata and the coal seam. The open-pit method is generally practiced where thick coal seams are overlain by thick or thin overburden; it is also used for mining steeply pitching coal seams. In the beginning stages of mining, considerable ...
