Rocklock Helps Increase Blasting Safety and Improve Fragmentation

At the core of the ABTI product line is RockLock, a high tensile, pliable plastic sphere that reduces and controls the random variables leading to borehole venting and stemming ejection. By improving confinement, RockLock improves aggregate fragmentation, enables the explosive to be loaded higher into cap rock and greatly reduces fly rock occurrences for a higher degree of safety. RockLock also delivers greater confinement for enhanced vibration control when used in decking applications.

Benefits:

  • Greater Safety
  • Improved Fragmentation
  • Higher Loads for Hard Cap Rock
  • Extended Hole Patterns
  • Blast and Dust Reduction

How To Use Rocklock Stemming Plugs

 

1.

Rocklock is partially filled  1⁄2 – 1/3 full with stemming. ABTI recommends that clean, crushed angular stone 1/10th the borehole diameter be used for stemming material.

2.

Approximately 1-1/2 times borehole diameter is loaded with stemming.
i.e. for 4 inch diameter borehole, 6 inches of stemming are filled.

3.

 

Rocklock is dropped down borehole.

4.

 

Fill stemming to top of hole.
