What is rotary drilling?

Rotary drilling is a general method in drilling in which a string of drill pipe is hung from a derrick and turned by the engine. Rotary cutting is also used to drill small boreholes in soft rocks. For medium to hard rocks, rotary crushing is used. Ai rotary drilling is used to drill deep boreholes in rock formations.

How does a down-the-hole drill work?

In down-the-hole drilling a drill rod is fitted with a hammer at its lower end. The hammer, which is mounted on the drill bit, is activated through the addition of compressed air and driven into the ground – simultaneously rotating and impacting. A flushing current collects the loosened drill cuttings and conveys them upwards.

What is a drilling rig?

Drilling rigs are complex mechanical structures designed to drill through the Earth’s surface to access oil, gas, water, or minerals. One of the most critical components of a drilling rig is the rotary system which is responsible for rotating the drill string and the drill bit to cut through rock formations efficiently.

What is a DTH drilling rig?
