What is a Drifter?

You get two main types of Drifters also known as a Rock Drill – Hydraulic Drifter and Pneumatic Drifter (air). In this article we will be focusing on the HYDRAULIC DRIFTER used on Drill Rigs for Surface and Underground mining activities.

A hydraulic Drifter or Rock Drill is a high frequency hammer that uses shock wave transmission (Percussion), Rotation torque and water/air flushing to allow a drill bit to penetrate rocks. With years of advancement in materials and hydraulic technology there isn’t a cheaper, safer and faster way to drill into rocks to depths of 2m to 24m vertically or horizontally.

Below is a video on basic drilling principles that are applicable to surface and underground drilling.

Basic drilling Principles

Where are Hydraulic Drifters used?

Surface and Underground Drill rigs

Surface Mining and Underground Mining

There are two main types of Drill rigs that use hydraulic drifters, Top hammer drills: Crawler drills that are used for opencast mining; and Drill jumbos that are used for operations such as tunnel and production drilling. Both types are mainly used to drill holes for charging explosives for blasting or roof support for safety.

Hole Diameter:

Also know as bore diameter (Internal Diameter): Hole Diameter varies depending on application, drifter power (kw) and rock hardness. On average hydraulic drifter can drill holes diameters ranging from +/- 24mm to 178mm.

Hydraulic Drifter Maintenance at Insumbi:

Hydraulic drifter Repairs

Hourly Maintenance is key:

When drilling the drifter begins to wear on certain internal components, there are strict hourly service intervals that when done saves companies money on repairs and catastrophic failures in the future.

The only way a Drilling Contractors/Mines or Construction Sites can save money on repairs is a strict a maintenance schedule for all drifters and drill Rigs.

Daily Maintenance should be carried out by a qualified site mechanics that have gone through our training course.

Drill Operators should be certified and re-certified when there has been site abuse identified through our rigorous failure reports and oil analysis that we issue to our customers.

Preventative Maintenance

400hr 800hr 1000 hr

That’s where Insumbi Technical Business fits in.
