Argentina's mineral wealth spans across diverse terrains—from the high-altitude Lithium Triangle in Salta and Jujuy to the deep gold, silver, and copper deposits in San Juan and Catamarca, down to the infrastructure projects in Patagonia. Reinforcing mine ceilings and tunnel walls in these geological environments requires advanced engineering solutions. The tectonic stress fields of the Andes Cordillera introduce complex structural behaviors, making friction rock stabilizers (split sets) the primary choice for ground control.
Unlike rigid concrete or chemical grout systems, split sets dynamic friction-anchored support reacts to geological shifts by flexing without snapping. This makes them highly effective in rock masses characterized by low to moderate Rock Quality Designation (RQD) values and frequent seismic events.
Operating at altitudes exceeding 4,000 meters above sea level presents challenges for mine safety. Lower air density limits the performance of traditional pneumatic machinery, requiring higher-efficiency air compression systems. To address this, our installers are calibrated for optimized pneumatic and hydraulic flow rates, ensuring steady impact force even in low-density atmospheres.
Additionally, the high salinity of lithium brine mining fields in northern Argentina accelerates steel corrosion. This necessitates specialized metallurgical coatings, such as hot-dip galvanization and thermal-bonded epoxy coatings, which extend the operating life of split sets under severe chemical exposure.
The split set stabilizer is a high-tensile steel tube slotted along its entire length. When driven into a pre-drilled borehole of slightly smaller diameter, the slot compresses, generating continuous radial force against the borehole wall along the entire length of the tube.
Our proprietary steel composition features a high yield-to-tensile ratio, allowing the tube to compress and expand dynamically under stress without structural failure. This creates a highly secure, immediate mechanical grip that improves over time as surrounding rock shifts and settles.
Correct installation is key to peak performance. Using incorrect driver adaptors can cause the stabilizer collar to deform, compromising structural integrity. Our high-durability dolly pushers and drivers are engineered to fit standard jumbo drills, pneumatic jackhammers, and bolting rigs used in Argentine mine sites.

Navigating the complex import and custom clearing regulations in Argentina (including SIRA system details and local tax structures) requires an experienced manufacturing partner. We offer end-to-end documentation support to facilitate smooth shipping and customs clearance.
All our reinforcement systems comply with both global standards (ASTM, ISO) and local Argentinian safety regulations, including those enforced by the Superintendencia de Riesgos del Trabajo (SRT) and local provincial mining secretariats.
Split sets provide immediate, full-length friction-based anchorage and allow for geological movement without fracturing. Resin rebar bolts offer high rigid strength but can shear under dynamic geological shifts and require curing time. In seismic zones like the Andes, split sets are preferred for dynamic rock mass environments.
The anchorage capacity depends entirely on the interference fit. If the borehole is too large, the tube does not compress enough, resulting in reduced load-bearing capacity. If the borehole is too small, the driver tool may deform the bolt collar or split the steel during insertion. We supply precise drilling guides for our 33mm, 39mm, and 42mm systems.
Lower air pressure at high altitudes reduces the performance of standard pneumatic jackhammers. To maintain proper driving force, we adjust our driver systems to work at optimal kinetic levels, ensuring consistent installation even in low-density air environments.
For lithium mines in Salta or Jujuy, we supply hot-dip galvanized coatings according to ISO 1461, as well as specialized epoxy coatings. These provide superior resistance to high-salinity water, helping prevent premature corrosion of the structural steel.
