History of Explosives and Blasting Mining Engineer First

In the US and Canada alone, blasters use more than 6 billion pounds of explosives and 75 million detonators per year. Coal mining accounts for twothirds of consumed explosives of which more than 80% of it is ANFO. Today, sophisticated explosive materials and new technologies are being utilized to improve the quality of life for all of us.

Overview

In the AntiPersonnel Mine Ban Convention (also known as the Ottawa Treaty) and the Protocol on Mines, BoobyTraps and Other Devices, a mine is defined as a quot;munition designed to be placed under, on or near the ground or other surface area and to be exploded by the presence, proximity or contact of a person or vehicle.quot; Similar in function is the boobytrap, which the Protocol defines as quot;any device or material which is designed, constructed or adapted to kill or injure and which functions unexpectedly when a person disturbs or approaches an apparently harmless object or performs an apparentl

Facts About Land Mines CARE

Land mines are containers of explosive material with detonating systems that are triggered by contact with a person or vehicle. They are designed to incapacitate that person or vehicle through damage caused by an explosive blast, fragments, (or, in the case of some antitank mines, a jet of molten metal).

Explosive

Overview

The largest commercial application of explosives is mining. Whether the mine is on the surface or is buried underground, the detonation or deflagration of either a high or low explosive in a confined space can be used to liberate a fairly specific subvolume of a brittle material in a much larger volume of the same or similar material. The mining industry tends to use nitratebased explosives such as emulsions of fuel oil and ammonium nitrate solutions, mixtures of ammonium nitrate prills (fertilizer pellets) and fuel oil (ANFO) and gelatinous suspensions or slurries of ammoniu

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 engineering application.
