Splitset

Split Set® Friction Rock Stabilizers - Rock Bolts for Reliable Ground Support Split Set® friction rock stabilizers are manufactured by International Rollforms, Inc. for underground or above ground applications in mines, tunnels, slopes, or wherever reliable ground support is needed. Our friction rock bolts produce superior holding power due to their unique design that exerts pressure against the rock over its full contact length immediately upon installation. When ground shift occurs, our rock bolts conform to the changing ground conditions. The result is a tight grip that actually grows stronger with time and ground movements, providing reliable ground support. It never needs tightening.

Our friction rock stabilizers are a simple system requiring only 2 parts, a tube and bearing plate. Fast, easy installation takes usually less than a minute - just drill and drive. Split Set® stabilizers come in 3 models. They are available in lengths and sizes to meet your needs and are made of standard, galvanized, or stainless steel.

1. Corrosion Resistance:3CR12 stainless steel is known for its excellent corrosion resistance, making it particularly suitable for underground mining environments where exposure to moisture, water, and corrosive elements is common. This resistance helps to maintain the integrity of the split set over time, reducing the risk of degradation and ensuring a longer service life.
2. Strength and Durability:Stainless steel, including 3CR12, is known for its high strength and durability. This is crucial in underground mining, where ground conditions can be challenging. The split set acts as a ground support system, providing stability to the surrounding rock. The use of a self-drilling design further enhances the efficiency of installation, reducing the need for additional drilling equipment.
3. Ease of Installation:The self-drilling feature of the split set simplifies the installation process. This can lead to significant time and cost savings compared to traditional methods that require separate drilling and installation steps. The ability to drill and install in one operation enhances the overall efficiency of ground support implementation in underground mining.
4. Reduced Downtime:The quick and efficient installation of a self-drilling split set helps minimize downtime in mining operations. Faster ground support implementation means less disruption to mining activities, allowing for smoother and more continuous mining processes.
5. Versatility:3CR12 stainless steel split sets are versatile and can be used in various mining applications. They are suitable for stabilizing different types of rock formations and ground conditions. The adaptability of these split sets makes them valuable in a range of underground mining scenarios.
6. Long-Term Cost Savings:While the initial cost of stainless steel split sets might be higher compared to alternative materials, their corrosion resistance and durability contribute to long-term cost savings. The reduced need for frequent replacements and maintenance offsets the higher upfront investment.
7. Safety Considerations:The stability provided by self-drilling 3CR12 stainless steel split sets enhances overall safety in underground mining. By preventing rockfalls and ground instability, these support systems contribute to a safer working environment for miners.
