cement grouting for ventilation raise construction

Ventilation Raise Construction in a Gold Mine

Location: Dubreuilville, ON
Sector: Mines
Category: Cement Grouting

Description

An expanding underground gold mine required the construction of a new ventilation raise through fractured, water-bearing rock conditions.

Working in conjunction with a diamond drilling contractor to drill perimeter holes parallel to the alignment of the planned raise, Multiurethanes supplied cement grouting equipment and experienced personnel for cement grouting work to fill open fractures prior to drilling the pilot hole and reaming of the ventilation raise to the final diameter.

The provided cement grouting equipment consisted of water supply equipment, inflatable borehole packers, electromagnetic flowmeters, progressive cavity pumps and paddle grout mixers.
