To address the key challenges of linear mining, METDEEM breakers mounted on excavators enable precise tracking of narrow ore veins, avoiding waste rock dilution. They replace explosives in restricted areas, reduce large boulders after blasting for easier haulage, and allow simultaneous road construction. This combination boosts mining efficiency, cuts dilution costs, and provides unmatched flexibility for safe, continuous operation along the vein direction.
The real dilemmas and demands of mining customers
In the global mining industry, most metal veins such as iron, copper, and gold extend in a linear pattern. To reduce stripping costs, operators typically only extract the veins themselves and are reluctant to waste resources in clearing the surrounding waste rocks. This reality brings about three core pain points:
- Challenges in precise mining: How to operate efficiently along narrow mineral veins while avoiding missed mining or the inclusion of waste rock?
- Blasting limitations: In many areas, the approval process for explosives is strict, the risk of vibration is high, and environmental pressure is significant.
- Transportation bottlenecks: It is difficult to load large chunks of ore onto vehicles, resulting in low transportation efficiency and high costs for secondary crushing.
To address these challenges, METDEEM’s hydraulic breaker offers a mobile solution of “excavator and hydraulic breaker” – it is not just a breaking tool, but a versatile mining solution capable of achieving linear tracking mining, flexible road repair, and immediate shaping.
Linear Ore Vein Mining – The Precise Combination of Excavators and Impact Hammers
Flexible tracking along the direction of the ore vein
The excavator can move continuously along the direction of the ore vein, and the hydraulic breaker directly strikes the ore body to break it into small pieces. Compared with blasting, the hydraulic breaker can provide highly precise breaking control, avoiding over-digging or under-digging, maximizing the extraction of ore materials while minimizing disturbance to surrounding waste rock, and significantly reducing the amount of ineffective stripping.
While mining, build roads simultaneously to enhance transportation efficiency
The excavator equipped with a hydraulic breaker can not only carry out mining operations but also repair the transportation roads simultaneously. The hydraulic breaker can quickly crush the protruding rocks on the road surface, allowing transportation vehicles to pass smoothly. This integrated mode of mining and transportation significantly reduces the time for auxiliary operations.
Dual Applicability in Both Non-explosive and Explosive Areas
Non-Explosive Areas: The Perfect Alternative Solution
In locations where there is a strict control over use of explosives and even prohibition of their use, for example in Europe and certain Australian states, digging with excavators and the use of hydraulic breakers have proved to be the most popular means of mining. In this case, the METDEEM hydraulic breaker does not require any approval for blasting since it breaks the ore bodies directly. It is able to work continuously with no debris in flight or excessive vibration.
Explosive Areas: Essential Secondary Crushing Equipment
Even in countries that use explosives such as in some mines in Africa and South America, after a large blast, large chunks of ore with diameters exceeding 1 meter or even 2 meters will be produced. These large chunks cannot enter the coarse crusher or be loaded into standard dump trucks. At this point, the METDEEM hydraulic breaker is used for secondary crushing, rapidly reducing oversized rocks to 30–50 cm pieces in size to ensure smooth logistics.
| Comparison item | Only blasting | Blasting and METDEEM breaker | Only METDEEM breaker |
| Applicable scenarios | Allow blasting, away from residential areas | Requires secondary crushing of large rocks | No explosives or sensitive areas |
| Mining flexibility | Low, difficult to control boundaries | High, breaker can precisely shape | Maximum, can dig along the vein precisely |
| Transport efficiency | Many large rocks, prone to traffic jams | Uniform crushed rocks, quick loading | Directly extract small pieces, highest efficiency |
| Overall cost | Explosives , approval and secondary crushing | Medium, reduces the amount of secondary crushing | No explosives cost, controllable fuel consumption |
Core Technical Advantages of METDEEM interruttore idraulico
To adapt to the harsh working conditions in mines, the METDEEM interruttore idraulico focuses on addressing the three most critical issues that customers are concerned about: durability, impact force, and ease of maintenance.
- Long-LifeChisels: Made of 40Cr special steel with through-hardened heat treatment, with a hardness of HRC 58°, their lifespan is 2 to 3 times that of ordinary brazing rods, reducing the frequency of replacement.
- Anti-shear piston technology: 20CrNiMo material anddeep cold treatment, combined with an optimized hydraulic system, it suppresses lateral vibrations and avoids cylinder body scratches.
- Imported seals: Resistant to high and low temperatures, anti-wear, with a maintenance cycle extended by more than 30%, reducing downtime losses.

Domande frequenti
Q: Can the METDEEM breaker remain stable during impact on uneven mining veins?
A: Yes. We employ a special buffering structure, resulting in low recoil force. The excavator’s boom can be flexibly adjusted in angle, enabling stable operation even on slopes or narrow mining veins.
Q: For the large rocks that have already been blasted, how many tons of rock can your interruttore idraulico process per hour?
A: Taking the METDEEM 140 model as an example, for secondary crushing of medium-hard large-sized ore, it can process approximately 60-100 tons per hour. The exact amount depends on the size of the rocks and the operator’s proficiency.
Q: How to solve the problem that the sealing parts of the breaker are prone to damage when it is in the dusty environment of the mine for a long time?
A: We use imported high elasticity and wear-resistant sealing parts and optimize the dust-proof design. At the same time, we suggest that customers add grease daily and clean the drill rod guide sleeve regularly, which can significantly extend the service life of the sealing parts.
