Open cut or surface mining in coal is a suitable choice when coal seams are closer to the natural surface. It is an effective method of retrieving a higher proportion of coal when compared to underground mining. The basic process involves: 1) Exploration. 2) Geological Modelling. 3) Mine Design

The higher productivity for open pit mining equipment also lowers costs. The necessary underground equipment for maintaining productivity is more expensive on a unit basis capacity than corresponding open pit equipment. Furthermore, the large production scale and share number of open pit mines have provided the opportunity for manufacturing

Opencast Mining Know More. Coal is mined either by surface methods open-cut or open-cast mining or by underground techniqu In surface mining, all of the rock from the ground surface to the top of the seam material referred to as overburden is removed and set aside to expose the coal, which is then taken out and transported from the mine for preparation and use Figure 11
