Rock Drilling Rig Flushing

What is a spiral flush drill & how does it work?

Mincon’s market-leading air control technology, Spiral Flush, is the safest way to drill in sensitive ground and tight urban spaces. It makes drilling safe by not discharging any air directly towards the soil – without sacrificing efficient flushing and fast drilling speeds in any hardness of rock.

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 Tei rock drills?

TEI Rock Drills provides dust suppression systems that easily inject water into the drilling air, reducing dust. This system helps to comply with local and federal safety regulations regarding dust and silica.

Can you drill in rock?

It is possible to drill in all kinds of rock. It is possible to use most power alternatives to drive the equipment (i.e., air, electricity, diesel). Rotary drill bits produce smooth hole walls that make subsequent packer installation easier for rock grouting.

What type of drilling system do rigs use?

Rigs often can use a variety of rock and overburden drilling systems and all flush types. Drill rod/casing lengths as little as 1 m or as much as 20 m can be accommodated depending on project constraints.

Can air flush be used in percussion drilling?

For percussion drilling (down-the-hole), air flush alone is permitted only in “saturated rock” where the groundwater inflow is substantial enough to keep the fissures clean. This is, however, poor practice in rock with weathered, clayey or silty materials which may clog fissures and create foundation damage through overpressurization.
