The photograph below illustrates the Increased Fragmentation routinely achieved by users of Stemplugs. By confining the explosive energy in the borehole you will receive greater impact from the explosives. We have published reports attesting to increases of 50% in fragmentation. There is also an increase in microfractures in the broken rock, These microfractures will result in easier crushing of the aggregate. We have numerous reports of 20% reductions in electrical energy used in crushing. The muck pile will be easier to dig and there will be less wear and tear on the tooling. The side benefit to containing the explosive energy in the ground is that you also get reduced Fly Rock, Air Blast, and Dust.
You will receive a bundle of benefits at a very good price when you use StemPlugs in your blasting operation.
