What explosives do mining companies use?
Blasting agents account for almost 99% of the explosive materials used. ANFO, ammonium nitrate and fuel oil, is the most common explosive.
ANFO, pound for pound is as powerful as dynamite and is less expensive per pound and less sensitive to initiation and therefore safer to use.
How many types of explosives are there in mining?
Permissible explosives are classed as granular, gelatinous, and water- gel types. Granular explosives (table 1) are well suited for use in mines that are relatively dry.
What explosives are used in underground mining?
Two types of dynamite are used in Karadon TIM as explosives, namely methane-safe permissible dynamite and gelatine dynamite.
Methane-safe permissible dynamite is primarily suitable for underground coal blasting operations and for the blasting of soft rocks.
Do mines still use explosives?
Explosives have been the primary method of breaking and loosening rocks since the introduction of black powder.
Today’s wide range of commercial explosives are safer to use but still represent a major hazard due to the enormous amount of energy that can be rapidly converted into gases at high temperatures and pressure.
