Different Types of Explosives Used in Mining
· In other words, are we using the same explosives in mining and warfare? Well, yes and no. From the ninth century AD (though the historians are still uncertain about the exact date of its invention) to the mid1800s, black powder was the only explosive available. A single type of explosives was therefore used as a propellant for guns and for blasting purpose in any military, mining and civil ...

Underground Mining
Matching explosive energy to geology enables expanded patterns without affecting fragmentation. This in turn increases the drilling yield, providing more tonnes per drill metre. Products and procedures for safely sleeping blasts allow less frequent and larger blasts, reducing production delays and increasing blasted inventory without employing more drills or blast crew resources.

pattern. The rocks are middle Precambrian in age, about billion years old, and consist of layered iron carbonates and iron silies. Iron ore mining first occurred in Minnesota on the Vermilion Iron Range in 1884 followed by the Mesabi Iron Range (1892), Cuyuna Range (1911) and the Fillmore County District (1941). The first mines on the Mesabi exploited the socalled "natural ore ...

Iron Ore Mining | Techniques | Metal Extraction
Iron ore mining can be broadly divided into two egories namely 1) manual mining which is employed in small mines and 2) mechanized mining is suitable for large iron ore mines. Manual mining method is normally limited to float ores and small mines. Mining of reef ore is also being done manually on a small scale. The float ore area is dug up manually with picks, crow bars, and spades, and ...

Using Low Density Explosives In Iron Ore Appliions
Using Low Density Explosives In Iron Ore Appliions REDUCING THE OVERALL COST OF BLASTING AT IRON ORE MINES Dyno Nobel developed BlastLite® and TITAN® as cost effective solutions for blasting weak to medium strength rock in Iron Ore mines. The key to BlastLite lies in its ability to form a homogeneous blend without the need to use an emulsion matrix as a binding agent. .

Chapter 8 BLAST DESIGN
Delay patterns, and varying the hole array to fit natural excavation topography, allow for more efficient use of the explosive energy in the blast. Benches may be designed and carried forth with more than one face so that simple blasting patterns can be used to remove the rock. In the illustration that follows (Figure 84) shows a typical bench cut with two free faces and fired with one delay ...
Our underground mines
Sublevel caving is an effective mining method for steep ore bodies, allowing maximum extraction from the ore body with a high degree of safety. The mining in the underground mines takes place in a 'drillandblast cycle', a process that includes activities ranging from development to hoisting during the course of a day. Underground mining takes place in several stages: Drifting. In order ...
