2016-11-11 · detonation delay, meaning there can be up to six seconds between the first and last detonation. One charge can produce between 500 and 20,000 tonnes of ore. At the Aitik open-pit mine, the holes are 16-17 metres deep, and here a normal round produces approximately 700,000 tonnes of extracted rock. Loading At a number of Boliden''s under-
go off 1. Of an explosive device, to explode. Run! The bomb in the building could go off at any moment! 2. Of an alarm, to enter into an active state, typically resulting in a loud noise or other indication. The whole building had to evacuate because the smoke alarm went off. The silent alarm went off at the bank, we''d better check it out. 3. To depart ...
The Detonation Tube (pictured here) is a national facility established with funding from the Australian Government and ACA Low Emission Technologies (ACALET).

Change in the reactivity gradient. A related situation that disrupts a detonation is propagating into a gradient of reactivity which goes in the direction from a stronger to a weaker detonation.
After detonation, workers do the extraction by 14 or 60 tonne trucks. These trucks have a priority in transport because they are big and heavy and also if they stop, the production stops. Trucks are going to the underground space where machines do the process of crushing.
2020-7-1 · It can not only improve the rock crushing efficiency, but also realize the impact of blasting vibration (Katsabanis et al., 2006). The purpose of the delay blasting is to control the detonation time and detonation sequence of the detonator to achieve the desired rock fragmentation effect and reduce the intensity of the blasting vibration ...
