The operation of removing overburden and extracting mineral is done by one of the following methods: 1. Manual Quarrying: In this case manual labour is employed. Small drilling machines, drilling 1.2 m to 1.8 m deep holes, 37 mm diameter, are used and the holes are blasted with gun-power or other explosives.
