6 FAQs about [100b Air volume for down-the-hole drilling rig]

How is air calculated for rotary blast hole drilling?

Air Calculation For rotary blast hole drilling, PDB Tools is focused on three major factors: Air delivery, Weight on Bit, and RPM. The delivered air needs to have sufficient volume, at the proper pressure to assure optimum bearing life when drilling with recommended Pulldown and RPM’s.

How do you calculate the annular area of a drill hole?

“If you’re simply doing vertical air drilling, and it’s not reverse circulation, you need to have enough air velocity to lift the cuttings out of the hole. That is a calculation of the borehole diameter minus the drill pipe diameter, giving you the annular area.

What is the best drill rig?

This rig is a rugged, verstile machine which can take on tough tasks in rough territory. The AirROC D50 is a Down-The-Hole drill rig which is built to take on steep slopes and uneven ground. Ample hole range thanks to the unique VL 140 rock drill which allows for drilling of 102 mm (4") diameter holes.

Why do we use air while drilling?

So why use air while drilling? With air drilling bits, 20 to 30 percent of the air supplied for flushing the drilled rock out of the borehole is actually diverted around the nozzles in the drill bit to cool the bearings of the drill bit. Each roller cone has its own bearing that heats up under pressure and friction loads while drilling the rock.

How much Air do you need to clean a drill bit?

The following are recommended minimums for adequate bit face cleaning: 6″ bit = 475 cfm of air 6-1/2″ bit = 525 cfm of air 7-1/2″ bit = 650 cfm of air 8″ bit = 750 cfm of air In practical applications, the formula gets you close enough to start your drilling project.

What psi should a drill rig use?

The industry standard used to be 350 psi, but in a lot of applications now – in underbalanced drilling and other applications – it’s gone up to 500 psi. That puts it in a niche where there are fewer players in the market that can provide that type of equipment, but it can help make for a more efficient and effective method of drilling.”
