Types Of Drilling Operations

Drills are classified into two main types. One type is used to generate rock chips, and the other one produces core samples. These methods are ideal for certain drilling operations. Each drilling operation has its pros and cons. Thus, you need to define what you want before the drilling operation or when buying Custom Coring Drills by KOR-IT. Here are popular classifications of core drilling operation.

Auger drilling

This type of drilling operation uses a helical screw. This aadsCAxASscrew is placed on the ground and rotated. Consequently, the blade of the screw lifts the earth to a bore hole level. This type of drill is ideal for soft structures, in areas with weathered rocks and unconsolidated materials. Auger drilling is a fast and cheap method of drilling.

Air blast drilling

Air blast drilling is commonly used in mineral extraction. Also, it can also be used in water bore drilling and the mining industry. It can also be used in blast hole drilling. During the drilling process, the drill applies a pneumatic reciprocating unit that resembles a hammer. With this tool, a bore is made on the surface of contact. Different types of drill bits are used for this operation. Air is used to collect the cuttings to the surface of the ground.

Air core drilling

This method is appropriate for unconsolidated grounds. This is because fresh rock hinders tungsten blades from penetrating into the ground. This method uses tungsten blades and hardened steel to drill a hole. The drill has three blades that are responsible for cutting unconsolidated ground. Once drilling is over, the cuttings are removed by compressed air, which is injected via the holes.

Cable tool drilling

However, this method has been faced out but is the most suitable way of drilling water wells in bed-rocked areas. The force applied during drilling breaks down the rocks into small units. Consequently, water finds its way in the ground surface over rotary.

Diamond core drilling

This method is applied in reverse circulation drilling and in extraction processes. During the extraction process, an annular diamond- impregnated drill gets attached to hollow drill rods. This cuts a cylindrical core into the rock. The process is usually slow since it is used on hard grounds. Also, this slow pace drilling helps to lengthen the life of drill bits and rods.…
