Product Description
Product Description
Typically, the loss of explosive energy through stemming ejection reduces the performance of the blast. The fundamental theory promoting the use of stemming enhancement plugs is that they could potentially improve the effectiveness of stemming material in the blast hole. This would, in turn, better contain the explosives energy within the rock mass, and yield a more controlled and efficient blast event.
The three keys to efficient blasting are:
1. Energy level ? the amount of available energy in the explosive product
2. Energy distribution ? the optimised linear distribution of the explosives
3. Energy confinement ? the optimised burden to energy ratio
The optimum stemming column height is determined so it provides proper energy confinement while still allowing for maximum explosive energy distribution.
The measure of the potential effectiveness that the available explosives energy has to break and displace the rock mass is directly proportional to the effective burden that energy must overcome. This relationship is a crucial element in basic blast design. An accurate controlled sequence of hole detonation is a fundamental design parameter, having a major direct effect on overall blast performance. Any variation in hole detonation timing, results in that hole being fired prior to or after its nominal firing time. The hole-to-hole detonation could still remain properly sequenced or holes could potentially detonate totally out of sequence. This will result in burden to energy relationships that can have adverse impacts on the performance of a blast.
The results of these impacts have been witnessed in the past as:
1 Poor rock fragmentation
2 Large amounts of oversize
3 High ground vibration levels
5 Flyrock incidents
6 High downstream processing costs
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.
