difference between open pit and open cast mining

The Advantages of Open Pit Mining | SciencingOpen pit mining does offer some advantages over traditional deep shaft mining. Pit mining is more cost effective than shaft mining because more ore can be extracted and more quickly. The working conditions are safer for the miners because there is no risk of cave in or toxic gas. Open pit mining

Opencast Mining - an overview | ScienceDirect The open pit or open cast mining method is the obvious choice for a property with a wide area of mineralization exposed or existing close to the surface and continuing to greater depths. The open pit exposes 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 blast pattern – Mining and BlastingBlast Design: This is meant to be a toolbox for blast design in conventional rock quarrying and open pit mines. This write-up is not meant to give straight answers to the blast design parameters, as every single quarry is unique. However, the general relations between the main blasting parameters; geology, blastability and explosives, will be applicable, and the estimation model is a very good
