Precision Drilling & Controlled Blasting

Service overview

Our drilling and blasting division is recognized as a leader in rock fragmentation across Tanzania’s premier mining belts. We deploy modern crawler-mounted blast-hole drill rigs equipped with automated feed controls and dust extraction systems. Working in close collaboration with certified blasting masters, our team utilizes advanced pattern design software to maximize rock fragmentation for mill throughput while strictly controlling ground vibrations, flyrock, and highwall fracturing.
