THE Australian Coal Industry’s Research Program (ACARP) has completed a research project to provide the underground coal mining industry with an understanding of explosive classification.
The project completed a number of tests to investigate the scientific basis of the British Health and Safety Executives Testing Memorandum.
Eighty ‘Type I’ tests revealed that a set of parameters could be used to identify if an explosive would cause an ignition in the gallery.
One hundred and eight deflagration tests of the ‘Type II’ cannon also revealed emulsion explosives were able to detonate in the cannon rather than deflagrate.
According to ACARP, the longer a receptor is subjected to elevated pressures, the higher the probability of deflagration.
