Components of DTH Drilling Rig

KH103 Diesel Integrated Borehole Drilling Rig Rotary Head With Air Compressor

Rig Structure: The rig consists of a sturdy framework or structure that provides stability and support during drilling operations. It is typically mounted on tracks or wheels for mobility and maneuverability.

Drill Mast: The drill mast is a vertical or inclined tower-like structure that supports the drilling assembly and provides guidance and control during drilling. It can be raised, lowered, and rotated to position the drill string accurately.

Drill String: The drill string is a series of interconnected drill pipes or rods that transmit the rotation and impact forces from the drilling rig to the drill bit. It includes components such as the drill pipes, subs, and the DTH hammer.

DTH Hammer: The DTH hammer is a percussion tool that delivers high-frequency blows to the drill bit. It is connected to the drill string and powered by compressed air or other drilling fluids.

Drill Bit: The drill bit is the cutting tool attached to the bottom of the drill string. It comes in various designs, such as button bits, ballistic bits, or flat face bits, depending on the drilling requirements and the type of materials being drilled.

Compressor: A compressor is an essential component of a DTH drilling rig. It supplies the high-pressure compressed air needed to power the DTH hammer. The compressor can be integrated into the drilling rig or provided as a separate unit.

Control Panel: The control panel is the central hub for operating and controlling the drilling rig. It allows the operator to monitor and adjust various drilling parameters, such as rotation speed, feed pressure, and airflow rate.

Support Equipment: Depending on the specific drilling requirements and conditions, a DTH drilling rig may be accompanied by additional support equipment. This can include air compressors, water pumps, mud systems, drill cuttings removal systems, and other auxiliary equipment.
