Different Types of Explosives Used in Mining

04/09/2019  Primary Explosives Can Be Easily Detonated Due to their extreme sensitivity to heat, friction, impact, static electricity. Mercury fulminate, lead azide or PETN (or penthrite, or more properly Penta Erythritol Tetra Nitrate) are good examples of primary explosives used in the mining industry. They can be found in blasting caps and detonators.

British Gypsum: Brightling gypsum mine

The British Gypsum Brightling mine, near the Robertsbridge wallboard plant in East Sussex, has been in operation since the early 1960s. In the 1970s and 1980s it supplied up to 0.8Mt/yr of gypsum to the Robertsbridge wallboard plant, first via an aerial ropeway system and then a 4.7km-long conveyor, which was installed in 1989. In the early 1990s the arrival of flue gas desulphurisation gypsum ...

Explosives and Detonators - Mining and Blasting

This process is called detonation. A litre of modern high explosive will expand to around 1000 litres within milliseconds (ICI 1997), creating pressures in a blasthole of the order of 10,000 MPa (1,450,000 psi). Temperatures range from 1650-3870oC and the velocity of detonation (VOD) is so high (2500-8000 m/s) that the power of a single charge is around 25,000 MW. 1.2 Classifications of ...

Understanding charging and blasting ... - Mining Technology

The process involves drilling several holes into the rock and filling them with explosives. The locations and size of these holes are carefully determined by mining engineers based on geological surveys, as well as the quantity of explosives. When detonated, these explosives cause the rock to collapse. Detonations are precisely patterned and timed to have the desired effect.
