Mining Mining Surface mining: It has been estimated that more than twothirds of the worlds yearly mineral production is extracted by surface mining. There are several types of surface mining, but the three most common are openpit mining, strip mining, and quarrying. These differ from one another in the mine geometries created, the techniques used, and the minerals produced.
#0183;#32;If an ore deposit is variable in grade then a large number of drillholes will be required to define the It is a very good technique for quickly drilling a large number of shallow (030m) holes across a deposit. Unfortunately, Drilling has to stop when groundwater is encountered as the hole quickly becomes clogged with mud.

In smallscale surface mining including small quarries, jackhammers are in common use but in larger quarries and open pits, various types of mechanised rigs are employed. They drill holes of up to 350mm diameter and lengths up to 60m. Blasting in a mine generally occurs in two phases, primary blasting and secondary blasting.

Open pit mining Mining Methods 5 Open pit mines are used to exploit low grade, shallow ore bodies. However, some pits are quite deep about 1 km. The mining rate is greater than 20,000 tonnes per day (tpd) but is usually much greater. Some pits operate at a rate of more than 100,000 tpd

Blast hole Drilling is a technique used in mining whereby a hole is drilled into the surface of the rock, packed with explosive material, and detonated. The aim of this technique is to induce cracks in the inner geology of the surrounding rock, in order to facilitate further drilling and associated mining activity.
