Should mining industries be required to adopt new chemical methods to lower blasting emissions?
Scientists have found that adding nitromethane to ammonium nitrate fuel oil significantly lowers harmful gaseous emissions after detonation. The process also improves the explosive performance compared to standard formulations.
Why it matters
Reducing carbon monoxide and nitrogen oxide emissions addresses significant environmental and safety challenges associated with standard blasting agents. This advancement balances emission control with higher detonation efficiency.
Researchers utilized Explo5 software to calculate theoretical detonation parameters, validating results with velocity of detonation tests. Nitromethane was incorporated at concentrations ranging from 4% to 9% by weight.
