What is down the hole drilling? Understanding the Process and Applications
Down the hole drilling (DTH) essentially involves a DTH drilling hammer at the bottom of a drill string. It relies on three elements for drilling holes: bit loading (weight), rotation, and air. These active elements combine to be efficient at crushing rock. As the drill string slowly rotates, the drilling hammer is forced into the rock repeatedly. Striking power is provided by compressed air driving a piston inside the hammer.
The Benefits of RC Drilling Tools: Discover Why They’re Essential for Modern Exploration
RC drilling has clear advantages over other top hammer drilling methods.Achieves greater penetration in hard rock than air core drilling, thanks to the percussive force and the strength of the RC drill bit.
How Reverse Drilling is Applied: Techniques and Applications
Reverse drilling is applied and consists , commonly employed in open-cut mines and used for pit grade control and in delivering useful insight for mine planning and blasting. It has an optimal depth of between 300 and 500 meters.
How Reverse Circulation Drilling Works: A Comprehensive Guide
Reverse circulation drilling, or RC drilling, is a form of percussion drilling that uses compressed air to flush material cuttings out of the drill hole safely and efficiently.
How to Select the Best DTH Drilling Bits: A Comprehensive Guide
The best DTH drilling bits are manufactured to match the shank and diameter of the DTH hammers. The bodies of quality bits are precision machined from alloy steel, heat treated to a specified hardness, providing surface compression for fatigue resistance, and then fitted with precision carbide buttons.
How to match the hammer to the correct pipe diameter
Pipe diameter should be close to the hammer diameter to provide optimum flushing, reducing the chances of getting stuck in the hole.
How to choose the correct rock drilling tools
Suitable for choose the correct rock drilling tools. The pneumatic percussion technique requires consideration of more than one type of tool to drill efficiently and profitably. A variety of factors, from hammer size to determining whether or not an economy hammer represents the best value, all figure into the hammer’s overall cost of operation on a given job.
