RC Drilling vs. Blast Hole Drilling in Zimbabwe - Understanding Borehole Drilling Methods

At Nakiso Borehole Drilling, a leading provider of borehole drilling services in Zimbabwe, we're committed to offering our clients the most suitable solutions for their specific needs. 


When it comes to borehole drilling, understanding the different methods available is crucial. This article delves into two prominent techniques: Reverse Circulation (RC) drilling and Blast Hole drilling.

RC Drilling: Unveiling Geological Riches

RC drilling, also known as rotary drilling with reverse circulation, is a sophisticated exploration technique used to extract rock core samples for geological investigations. Here's how it works:
  1. Drilling process: A drill bit crushes rock at the borehole bottom, and pressurized air forces the broken rock fragments (cuttings) upwards through the inner drill rod. Water may be used as an additional flushing agent.
  2. Sample collection: The cuttings travel through a cyclone separator, where the heavier core sample material is separated and collected for analysis.
  3. Applications: RC drilling is a valuable tool in mineral exploration, particularly for precious metals, base metals, and coal. It allows geologists to assess the type, quality, and quantity of mineral deposits at various depths.

Blast Hole Drilling: Precision for Efficient Excavation

Blast Hole drilling, in contrast to RC drilling, focuses on creating precise holes for controlled blasting in mining operations. Here's a breakdown of the process:

  1. Drilling process: A powerful drill rig bores a clean hole to the designated depth and diameter using a specialized drill bit.
  2. Explosives placement: Once complete, the hole is filled with precisely calculated explosives to fragment the rock mass efficiently.
  3. Applications: Blast hole drilling is essential in various mining activities, including quarries, open-pit mines, and underground mines. It facilitates controlled blasting for efficient rock removal and extraction of valuable minerals.

Five Facts About Borehole Drilling That You Need To Take Note Of:
1. Know Your Borehole Casings:The Preferred Borehole Casing In Zimbabwe Is Class 9 and 10 (Pressure Classes.)This is because Class 9 and Class 10 Casings are more collapse resistant. The strength of a Casing is often described as collapse resistance.

2. Borehole Drilling Depth: The exact depth, of where the water is located, cannot be established by the drilling contractor nor the Water Surveyor (Borehole Siter).

3. The Is No 100% Guarantee On Water: It is important to note that it is never a 100% guarantee that any hole will yield water, the amount and water quality can also not be guaranteed by the drilling contractor and water surveyor.

4. Borehole Siting or Water Surveying Is Important: Making use of a hydrologist or traditional water diviner will increase your chances of having a successful borehole that will yield a sufficient amount of water.

5. Know The Risks: The risk of the borehole drilling lies with the property owner. The client will still be liable for the drilling costs irrespective of a borehole yielding water or not.
