6 FAQs about [Standard smoke exhaust method for rock drill]

What are the different types of drilling methods?

There are two basic drilling methods—percussion and rotary—classified in accordance with the way in which mechanical energy transfers from the rig to the rock. Percussion Drilling In percussion drilling, the rock is made to fail by means of a piston that delivers rapid impacts to the drill steel, thereby transferring energy to the drill bit.

Are air rock drills safe?

Safe Operating Procedure Air Rock DrillThe instructions recommended within this d cument apply to normal risk conditions. If the Air Rock Drill is to be operated in a dangerous or hostile environment, the user/client is responsible for conducting an appropriate risk analysis and applying suitable cont

How do you control fugitive dust in a drill rig?

Dust-suppression and crushed-rock-cutting collection systems are available on many drill-rig models to help control fugitive dust. Rubber skirts and water-misting controls contain rock fines and dust around the blasthole collar. Cyclone mechanical dust collectors remove drill cutting from the hole collar and place them alongside the drill rig.

What is compressed air percussion drill?

Compressed air is used in sufficient volume to ensure a minimum velocity of upward airflow that both flushes drill cuttings and keeps the hole bottom cleaned. “Drifter” OTH percussion drills can be air- or hydraulic-operated and are generally limited to hole diameters of 5 inches or less.

What is a safe working zone for air rock drill?

t as per manufacturers recommendationsAll necessary guards & safety devices are in place protecting w ers from all moving & rotating parts. “Safe Working Zones” are clearly defined in all work sp ces where air rock drill is being used.

How does air flow affect blasting smoke distribution?

As the distance from the blasting working face increases, the volume of blasting smoke distribution gradually expands, and the smoke is constantly replaced with fresh air flow. The fresh air flow carries out high concentration of blasting smoke, gradually reducing the concentration of smoke.
