Blasthole Pre-treatment Lubricates, Seals
Blastboss released Holeguard, a multi-function blasthole pre-treatment that, the company reported, combats poor collaring, hole decay and wall instability. Holeguard is a concentrated micro-emulsion of water soluble co-polymers designed to deliver maximum drilling efficiencies by reducing friction, increasing cuttings removal, sealing drill collars for dust control and stabilizing blast hole walls to minimize wall collapse. Holeguard is supplied as a liquid dispersion formulation that reacts rapidly at minimal dosage rates, penetrating deep into the strata surrounding a blast hole and providing lubrication to the hole, increasing the lifting capacity for cuttings transportation and encapsulating water sensitive clays or shales, the company reported.
