Product Description

Product Description

Stemming is one of the major effective parameters of open pit blasting. "Stemming plugs" are the new technological development on the increase of blasting efficiency without changing the feature of explosives. They are used in the stemming zone of the blast hole to increase the containment of the explosive gasses.

The drilling and blasting operations in open pit mining and quarrying are two important cost elements, which must be considered to reduce with new technological developments. Beside of the cost of blasting, another important effect of blasting to be considered is the fragmentation of blasted rock. It has a very big influence both on the performance of loading equipment and on the cost of primary crushing if the blasted pile is a raw material of a consecutive process.

 

 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

Stemming plugs are a valuable tool. It pays to be open-minded and to evaluate new technologies.
Plugs work by creating a blocking effect within the drill hole by wedging the stemming material between the drill hole wall and our plug. Upon detonation of the explosives, the plug is forced upward into the stemming material and "locks up". The explosive gases and energy are prevented from traveling (venting) up through the drill hole, and instead are contained within the rock mass for milliseconds longer than non-plugged blasts!

Increased Fragmentation, Fracturing and Cap Rock Breakage. Reductions in Fly Rock, Air Blast, Stemming Ejection, Dust, Noise and Oversized Rock. These are all direct benefits and results of containing the blast energy within the rock mass for milliseconds longer than normal, simply by using.
