Ore Dressing Sympatec. Ore Dressing. The extraction of raw minerals begins with the mining of rich ores, which are then cut up in crushers and grinders.
When priming blasting agents with holes up to 2 1/2 inches in diameter, a full cartridge of high velocity explosives like 60 percent ammonia gelatin, gels, slurries, or cast primers with a
Only slurry or emulsion explosives, preferably bulk explosives to be used for hot hole blasting purpose. It is preferred that explosives charging may be started near the initiation point first, (i.e., load explosives in the sequence in which the blast will be fired first).
Nov 15, 2017 Key Laboratory of Deep Coal Resource Mining, Ministry of matching between explosive charge in blast holes and the wall rock can coarse grained sandstone, coal beds, siltstone, medium grained . blasting, the detonation of explosive in water produces smaller amounts of
An explosive charge is a measured quantity of explosive material, which may be composed of a single ingredient or a combination of two or more. The potential energy stored in an explosive material may, for example, be chemical energy, such as nitroglycerin or grain dust;
resulting decrease in the diameter of the explosives column, reduces the amount of explosive energy within the borehole. The blaster must use higher energy explosives to balance the lost energy. Necessary explosive energy adjustments at the borehole can be made to compensate for excessive toe, hard bottom, or cap rock.
In the mining of underground ore bodies, boreholes for the explosive dislodgement of the ore are frequently drilled upward into the ore formation. These upwardly extending boreholes (up holes) are charged with explosives with great difficulty, especially in chambers having high ceilings.
The type of explosives used ranges from free flowing bulk loaded ANFO in dry hole condition to high strength Emulsion explosives in wet hole condition. The charge factor / explosives consumption in this type of blasting is generally kept of the order of 0.1 to 0.25 kg / tonne of blasted ore.
Explosives Charger 1 Getman explosives chargers are versatile explosives charging vehicles designed to work in development drifting, production charging, up hole charging applications and more. They can be configured for ANFO charging, emulsion charging, or both.
