Blasting is the first step in the mining value chain, and any positive impacts made during blasting result in exponential downstream gains. In the case of manganese mining, reducing the amount of fines produced during blasting can lead to astronomical financial gains. This case study from a South African manganese mine demonstrates how a minor […]
Varistem® is a patented blast-stemming plug for mining, quarrying and civil blastingapplications. The plugs contain blast energy for longer, resulting in a range of benefitsdepending on how it is incorporated into your blast design. The Varistem® blast stemmingplugs are manufactured in a range of different sizes, catering for blasthole diameters from51mm to 203mm. Improvement In […]

Varistem® Stemming Plugs Trial Summary Introduction Flyrock is a significant safety and environmental concern in coal mining, particularly when blasting occurs near inhabited areas. This study aims to evaluate the effectiveness of Varistem® stemming plugs in reducing flyrock at Coal Mine X. The trial was conducted near a neighboring farm within a 500m blast radius, […]
Varistem® Blast Stemming Plugs Trials Iron ore fragmentation plays a crucial role in the efficiency of mining operations, directly impacting the performance of processing plants. The following study focuses on the improvement of particle size distribution (PSD) through the use of Varistem® blast stemming plugs in iron ore mines. By conducting comprehensive trials and comparing […]
The intent of the trial was to demonstrate the energy retention capabilities of the Varistem® blast stemming plugs through conducting a split blast on a production waste bench at a manganese mine in South Africa. The main results considered were to determine the difference in blast energy retention when using Varistem® with drill chippings as […]
