When blasting at the start of a tunnel or in a portal, several safety measures must be taken to control flyrock and ensure the safety of workers and equipment. First, accurate pre-blast assessments should be conducted to determine the optimal amount of explosive and the correct delay timing to minimise excessive rock movement. Proper confinement techniques, such as adequate stemming and using blast mats or protective barriers, should be employed to contain the blast and prevent flyrock based on

Blasting measurements. The fundamental principle of blast design is most often the distribution of an explosive in the rock, where “distribution” is considered to be a combination of blast pattern and explosive density. Powder factor is the relationship between a rock mass and the explosive used to fragment it; the term “powder factor” can be used to describe either the weight of explosive per unit volume (lb/yd³) or the weight of material blasted per weight of explosive (tons/lb). The weight of

Blasting World on Instagram: "This blast is a great example of blasting in tiers When firing multiple shots on different benches, whether once or in sequence, it’s important to initiate from the lowest blast pattern to the highest. In the case of flyrock or big ground movement, it’s much less likely to cover or cause a cutoff on the other blast patterns. Always start from the bottom up - Do it right the first time, only do it once💪🏼🧨 Thank you @bcarlsondrilling for the Badass Blasting You wan

AutoNext on Instagram: "In the Czech Republic, drivers on the motorway were shocked to see what looked like a Ferrari Formula 1 car blasting past traffic at high speed. But in reality, it wasn’t an F1 car at all, it was a Dallara GP2 single-seater, wrapped in a striking Ferrari livery from the Michael Schumacher era, complete with the number 7 decals. This isn’t the first time the mysterious driver has pulled such a stunt. Back in 2019, police caught footage of the same car on the same road, and
