Drilling and Blasting in Underground Mining GRT Review

4/1/2021· GRT’s 12X technology is an innovative example of a product developed to manage drilling dust at the source. The use of explosives in blasting poses danger of toxic gases. The most common are carbon monoxide and oxides of nitrogen. Blast fumes are quickly diluted to below toxic levels by the ventilation systems in underground mines.

Drilling and blasting Wikipedia

9/14/2005· Drilling and blasting is the controlled use of explosives and other methods such as gas pressure blasting pyrotechnics, to break rock for excavation. It is practiced most often in mining, quarrying and civil engineering such as dam, tunnel or road construction. The result of rock blasting is often known as a rock cut. Drilling and blasting currently utilizes many different varieties of explosives with

The hole story: the benefits of drill and blast Engineer

Changes in drillhole placement and blast timing can be performed before the drilling operator drills the holes. This approach allows for design changes before a single hole is drilled. If a high-precision guidance solution, such as Leica J2drill, is used to drill the holes, as-drilled data can feed into blasting simulators to adjust the blast design further before a shot is fired.
