Hogan Drilling have the experience and expertise, using the most up to date laser instrument to establish the exact burden that lies in front of the borehole. Getting the details right is imperative in achieving both a safe and cost efficient blast.
Accurate information about the blast geometry of a quarry rock face will have a significant effect on the success of blasting operations.
Using the latest laser, electronic and computer technique, our integrated survey system enables our shotfirers to accurately determine face profiles and plan borehole patterns with optimum burden. Having collected this information, our shotfirers can precisely match burden with explosive charge, optimising blast ratios, not only for each hole but along the entire length of each hole. This results in significant reduction in drilling and blasting costs through increased efficiency. It also allows our client to achieve the safest blast along with reduced vibration and air overpressure.
