Blasting Techniques Used in Underground and Opencast Mines The velocity of detonation under suitable conditions of confinement can be faster than 5000 m/sec. This is the principle behind the use of liquid oxygen (LOX) as explosive. LOX is used for removal of overburden as well as mineral in the quarries of coal as well as metalliferious mines. But its use is prohibited in underground coal mines.

Mining and Explosives Mines CanadaThe first fireworks were created in China over 1,000 years ago by mixing saltpetre (potassium nitrate), sulfur and charcoal to produce a black, flaky powder the first "gunpowder."Today, gunpowder is still used as a propellant for fireworks, along with a wide range of raw materials to impart assorted colours and effects. "The colours in fireworks are generated by the presence of metals such as copper, aluminium, magnesium, strontium and more,"said Arpin. Copper compounds produce blue fireworksaluminum makes silver and white flames and sparksmagnesium burns a very bright whiteand strontium salts give fireworks their red colour.

Drill and blast mining is a common method used to break up 'benches'of rock in order to send the smaller pieces of rock containing ore to the processing plant to further separate the valuable ore from the waste rock. As the name suggests, holes are drilled into a section of rock either above or below ground and explosives placed in the drill holes. The volume of explosive needed varies greatly between mine sites, depending on the mining method used as well as the rock type and hardness. For example, StrataGold Corporation's Eagle Gold Project, in Central Yukon, will use approximately 6,000 tonnes of explosives each year, according to an Explosives Management Planthat the company prepared and submitted to the Department of Energy, Mines and Resources and the Yukon Water Board. Mining companies carefully monitor the amount of explosives used to extract each unit of ore. The goal is to use as little explosive as possible and send as little waste rock through the processing plant a

Explosives are serious business and potentially hazardous. As a result, the production, distribution, trade, movement and use of explosives in Canada is highly regulated with all levels of government having important roles to play. The provinces and territories regulate the use of explosives, specifically where mines and quarries are concerned with a focus on worker health and safety. Where explosive terminology, storage or standards are concerned, provincial and territorial regulations usually link to the Explosives Act or other guidelines published by the federal government. Municipal bylaws regarding permissible fireworks often direct users to the List of Authorized Explosives, care of Natural Resources Canada. The Explosives Act, which covers the issuing of licences, permits and certificates to facilities that store, import, export, manufacture, test and sell explosives, is supported by an inspection program, a research laboratory and regulations to control explosives and chemic
