Drilling is set of processes for breaking rock to produce bore-holes/shot holes, sampling, and excavations and is used mainly for resource extraction. In drilling process a drill bit is used to cut a hole of circular cross-section in solid materials. Mining drilling is used for two main purposes: Exploration drilling which aims to identify the location and quality of a mineral, and Production drilling used in the production-cycle for mining. Drilling also helps in scientific studies of earth and sub surface.
There are three types of drilling method: 
1) Percussion—(a) Top hammer and (b) bottom hammer

3) Rotary percussion—(a) DTH – Down the hole drill (b) top hammer drill.
