Here removal of overburden and coal extraction proceed in parallel strips along the face of the coal deposit with the spoil being deposited behind the operation in the previously mined areas In open pit mining thick seams tens of meters are mined by traditional quarrying techniques Underground mining is used for deep seamsGet Price
The open pit is opening the orebody from the surface by separate removal of ore and associated waste rocks It is the most economic option for a deposit up to that depth where the economic ratio of ore and waste can sustain There are many advantages in openpit mining method namelyFull visualization of exposed orebody and negligible ore lossGet Price
Open pit and open cast methods employ a conventional mining cycle of operations to extract minerals rock breakage is usually accomplished by drilling and blasting for consolidated materials and by ripping or direct removal by excavators for unconsolidatedGet Price
