Full Rotary Drilling Rig in karst topography

n karst terrain, which is characterized by soluble rocks such as limestone, drilling is usually done using a full rotary rig. These RIGS are specifically designed to meet the challenges posed by karst formations.

A complete rotary drill consists of several key components:

 The drill bit is a cutting tool attached to the bottom of the drill string. It is designed to penetrate the karst strata to create a hole for further exploration or mining.

The drill string is a series of interconnected drill rods that transfer drilling fluid and rotary forces from the surface to the drill bit. It is made of strong and durable materials that can withstand the drilling process.

 The turntable is a rotating platform located on the drilling platform. It provides the rotational force required to rotate the drill string and bit.

 Mud pump is responsible for circulating drilling fluid (also known as drilling mud) down the drill string and back to the surface. Drilling mud helps cool and lubricate the drill bit, removes cuttings from the well, and provides stability to the well.

Mud tank is a large container containing drilling mud in the drilling process. It is equipped with various systems to control slurry properties such as viscosity, density and pH.

The derrick is a tall vertical structure that supports the drill string and provides stability to the rig. It is usually made of steel and is designed to withstand the forces applied during drilling operations.
