Mining & Quarrying
Durable performance in quarries and mining sites.
Durable performance in quarries and mining sites
In open-pit and underground mines and quarries, the work revolves around extracting ore and rock, reducing oversized boulders after blasting and removing the overburden. Hard, abrasive conditions strain equipment; uptime and safety determine productivity.
HKM attachments offer flexible solutions from blast-free primary breaking to secondary boulder breaking. With heavy-class breakers, drum cutters for controlled excavation and crusher buckets that size material on site, they keep efficiency high in mining and quarry operations.
Mining environments
The same attachment families work by different methods: underground within the limits of drift cross section and ventilation, on the surface under bench layout and seasonal conditions.
Underground Mining
Roof scaling, block breaking and profile work in an environment where the drift cross section, the ventilation and the haulage line set the rules. More work from fewer machines is the clearest productivity lever in this environment.

Blast-free ripping, boulder reduction and slope trimming along the production chain that runs from overburden removal to crusher feed. Bench layout and seasonal conditions decide the method.

Blast-free primary and secondary breaking
Works in blast-free primary breaking of hard rock and secondary fragmentation of oversized boulders after blasting. Eases overburden removal and permitting; heavy-class models are long-lived in abrasive rock.
- Boulders too large for the crusher plant are reduced on site by secondary breaking.
- Where blasting is banned or risky, the breaker takes over primary extraction.
- Oversized material blocking the loading line is broken without delay to keep the flow going.
Controlled excavation in medium-hard rock
Profiles and excavates in medium-hard and layered formations where conventional digging is weak and percussive systems fall short. Provides precision in slope and wall shaping with low vibration.
- Selective excavation follows the seam in medium-hard, layered formations.
- Slopes and pit walls are milled blast-free to the target profile.
- The excavated material comes out finely sized, easing loading and screening.
Surface and slope with axial milling
The vertical (axial) drum works with high material throughput in leveling wide surfaces and slope correction. Offers efficiency in precise in-pit work with blast-free, low-vibration excavation.
- The axial drum works at high throughput on wide slope and bench correction.
- In-pit roads and platform floors are leveled.
- Worn faces are renewed without blasting.
On-site sizing
Grinds extracted rock and ore to the desired size on site; reduces the need to haul material to a separate crusher plant. Keeps material flow continuous with fast sizing.
- Post-blast material is sized on site instead of hauling it to the crusher plant.
- In remote pit areas, a single machine covers the mobile crushing need.
- Material is prepared at the desired size ahead of screening.
High machine utilization
Lowers machine idle time with fast switching between breaker, bucket and ripper. Increases operator safety on tough quarry ground.
- The carrier switches between breaker, ripper and bucket in a short time.
- On rough quarry ground the operator keeps working without leaving the cab.
- A single carrier covers several jobs within a shift.
Blast-free loosening
Rips soft-to-medium layered or weathered formations and frozen ground without blasting. Provides large-volume loosening with high single-tooth penetration.
- Overburden is ripped away without blasting to reach the ore.
- The tooth is pulled along the bedding, prying the formation apart at its fractures.
- A production flow is set up that needs no blasting permits.
Frequently Asked Questions
Which attachments are used in mining and quarrying?
Heavy-class hydraulic breakers for hard rock, drum cutters for selective excavation, crusher buckets and rippers for material handling are common.
What to consider when choosing a heavy breaker?
Rock hardness, carrier tonnage and daily working hours are decisive. High impact energy and a robust body deliver output and life in quarry conditions.
Do you offer site-specific solutions?
Yes. For abrasive, dusty environments we recommend suitable tools and lubrication, and plan spare-part supply too.
