Surface Drilling In Open Pit Mining
Open pit copper mining - MAXAM
Open-pit mining is used when the orebodies are extensive and relatively close to the surface. The sterile/ore ratio is one of the factors which defines the exploitation method and the final dimensions of the mine cuts. In general, open-pit mining consists of a system to exploit open pits with multiple benches.

However, surface mining can be more environmentally-damaging than subsurface mining. Types of Surface Mining Open-Pit Mining. Known also as "open-cast mining", open-pit mining is the most common type of surface mining. Open-pit mines are enormous holes in the ground; created and increased by blasting and drilling rocks apart.
Open-Pit Mining Methods
Open-pit mining methods are applicable to mining ore deposits that apex at or near the surface. If the deposit apexes below the surface, the overburden and barren capping overlying the ore must be removed in advance of open-pit mining. The removal of this material is known as stripping. The stripping-pit limits must be extended beyond the limits of the ore pit to provide a bench, and the pit .

Equipment Selection for Surface Mining: A Review
A surface mine contains pits with mineral endowed rock (or ore). We extract ore that lies within the upper layer of the earth, from surface mines (Fricke, 2006) . This ore can include metals such as iron, copper, coal and gold. There are several methods of surface mining, including open-pit, stripping, dredging and mountain-top removal.
Surface Open-pit Mining - Mineral Processing & Metallurgy
