6 FAQs about [Rock drill secondary protection]

Should you use Epiroc hydraulic breakers for rock mining?

Rock mining companies all over the world have already had great success using Epiroc heavy-duty hydraulic breakers for primary rock excavation as a substitute for blasting. When you use Epiroc hydraulic breakers, you benefit from our many years of experience in assessing mining methods around the globe.

Are hydraulic breaker or drum cutter a good alternative for rock excavation?

The performance capacity and adaptability of heavy-duty hydraulic breakers or drum cutters make them an interesting alternative for rock excavation. Use of hydraulic breaker or drum cutter is more economical, than use of a drill rig and explosives. Heavily fissured rock sometimes makes it difficult to drill and blast.

Are hydraulic breakers suitable for secondary reduction?

Hydraulic breakers are particularly suitable for all quarries and mines where secondary reduction is needed. Wide range of breaker models together with capabilities of modern carriers makes our breakers competitive in all secondary reduction applications.

Do you need a hydraulic Ripper to break a rock?

When hydraulic breakers are used for primary breaking, secondary breaking operations are normally not needed - unlike with mechanical rippers when large boulders may occur more often. Before excavating open-pit deposits, we need to remove overlaying soils or rocks (overburden). This is done continuously or in phases.

How long should a drill hole be?

Drill hole diameters and bond lengths are based on geological conditions. Consult your geotechnical engineer for recommendations. Per PTI, the minimum grout cover over the tendon bond length shall be 1/2” (13 mm). Two barriers around plain bar in free-stress zone plus drill hole grout.

What is the difference between rock excavation and open pit mining?

In open pit mines, it extracts metallic or non-metallic deposits and bedded deposits like coal or in quarries; rock excavation extracts building materials like aggregates or stones in the dimension stone industry. Rock excavation applications in the construction industry include trenching, underwater dredging or excavation for foundations.
