Products Description
A successful rock anchoring resin capsule is more than just a chemical; it is the heart of a support system. To achieve maximum safety, the resin must be perfectly matched with the rock bolt type and the specific geological strata. At ZF Mining, we specialize in engineering rock anchoring solutions that ensure a reliable bond, whether you are working in soft coal, hard sandstone, or fractured shale.
Compatibility with Rock Bolt Types
Bolt TypeRecommended Resin CapsuleBenefitThreaded BarMedium to Slow SettingEnsures full encapsulation and high bond strength.Cable BoltsLarge Diameter / High ViscosityProvides massive load transfer for large excavations.Hollow Anchor BarsFast SettingIdeal for immediate stabilization and grouting.FRP BoltsLow-Temperature FormulaProtects the composite material while ensuring a firm grip.
Performance in Diverse Rock Strata
Soft Strata (Coal/Mudstone): Our rock anchoring capsules provide a gentle yet firm expansion to avoid damaging the borehole wall.
Hard Rock (Granite/Basalt): High-strength formulas designed to transfer immense loads to the stable rock mass.
Wet/Damp Conditions: Water-resistant resin ensures the anchoring integrity is not compromised by groundwater.
Ensuring Maximum Pull-out Resistance
The ultimate goal of a rock anchoring resin capsule is the pull-out strength. ZF Mining's capsules are designed to exceed the yield strength of the steel bolt itself, ensuring that the rock strata remain locked even under extreme seismic or blasting stress.
