Product Description

Can they improve blasting and productivity?

 

Of the various products introduced to improve blast performance, flyrock control and productivity, stemming plugs have been looked upon with some disbelief and uncertainty.

Typically, the loss of explosive energy through stemming ejection reduces the performance of the blast. The fundamental theory promoting the use of blast-improvement and containment plugs is that they could improve the effectiveness of stemming material in the blasthole. As a result, this would better contain the explosives energy within the rock mass and yield a more controlled and efficient blast.

The three keys to efficient blasting are:
1.Energy level - the amount of available energy in the explosive product.
2.Energy distribution - the optimized linear distribution of the explosives in the rock mass.
3.Energy confinement - the optimized burden to energy ratio.
The optimum stemming column height is determined to provide proper energy confinement while still allowing for maximum explosive energy distribution in the blasthole. The measure of the effectiveness of the available explosive energy to both break and displace the rock mass is proportional to the effective burden that energy must overcome. This relationship is a crucial element in basic blast design.

stemming plug for mining, quarrying, and civil blasting applications

 is a stemming plug for mining, quarrying, and civil blasting applications. The stemming plugs increase energy retention and utilization during blasting, resulting in a range of benefits:

Improvement in Fragmentation

Reduction of Flyrock

Reduction of Noise and Airblast

Downstream Productivity Gains

Significant Cost Saving

is available for all blasthole diameters ranging between 1.75 inches (45mm) to 2.17 inches (55mm).
Stemming plugs are a valuable tool. It pays to be open-minded and to evaluate new technologies.
