Features:
- Reliable functioning
- One conically tapered end
- Threaded at the other end
Superior Strength and Reliable SupportFeaturing a minimum yield strength of 250 MPa and ultimate tensile strength of 450-600 MPa, these resin grouted rock bolts effectively stabilize underground excavations. The robust construction with high tensile steel and reliable anchoring mechanisms ensures long-lasting performance and enhanced safety in demanding environments.
Efficient Installation and Optimal Load TransferResin grouted rock bolts are installed using rotational insertion with compatible resin capsules, forming a solid bond with surrounding rock strata. This method optimizes load transfer, providing secure, immediate support for roofs and sidewalls. The process minimizes installation time and improves overall operational efficiency.
Corrosion Protection for Extended Service LifeGalvanized or epoxy coatings provide exceptional corrosion resistance, making these bolts suitable for aggressive underground environments. Their durability is further supported by careful packaging, ensuring bolts arrive bundled and palletized ready for installation without compromise in quality.
FAQs of Resin Grouted Rock Bolt:
Q: How are resin grouted rock bolts installed in underground excavations?
A: Resin grouted rock bolts are installed through rotational insertion combined with a resin capsule compatible with the bolt diameter, typically 24mm. The rotational movement mixes the resin and hardener inside the borehole, allowing the bolt to be anchored securely in place after the resin sets.
Q: What is the primary use of resin grouted rock bolts in civil and mining projects?
A: These bolts are primarily used for roof and sidewall support in underground excavations such as coal mines, tunnels, and caverns. They ensure safety by transferring loads from unstable rock strata to a secure support system created via resin grouting.
Q: When should corrosion-resistant resin grouted rock bolts be chosen for a project?
A: Corrosion-resistant resin grouted rock bolts should be selected when the project involves underground or harsh environmental conditions that could damage unprotected steel. Their galvanization or epoxy coating enhances longevity and reliability in moisture-rich or chemically aggressive settings.
Q: Where are resin grouted rock bolts commonly applied?
A: These rock bolts are widely used in coal mining, tunnel construction, underground caverns, and various civil engineering projects across India and internationally. Their adaptability makes them suitable for diverse geological conditions.
Q: What is the benefit of using EN8 or IS 2062 grade high tensile steel in rock bolts?
A: Using EN8 or IS 2062 grade high tensile steel ensures the bolts provide superior strength, with minimum yield strength of 250 MPa and ultimate tensile strength between 450 and 600 MPa, thereby enhancing the safety and stability of underground structures.
Q: What process ensures the load from rock strata is effectively transferred to the support system?
A: The resin grouting process distributes load efficiently by creating a strong bond between the bolt and the surrounding rock, ensuring that forces from unstable strata are safely transferred to the support system.
Q: How is transportation of resin grouted rock bolts managed to prevent damage?
A: For transportation, the bolts are bundled and palletized, ensuring they remain intact and protected against physical damages, maintaining consistent quality from manufacturer or supplier to installation site.
