  • Introduction To Blasting Coal Mining Explosive Material

    Introduction To Blasting Coal Mining Explosive Material

    Explosives are substances which contain a fuel and a source of oxygen. They are able to very rapidly change state to produce a volume of gas much larger than the volume of the original substance. Low explosives burn more slowly than the speed of sound, from around 40m / s - 1500m /s. High explosives burn supersonically - the gas already produced cannot get out of the way of gas being produced ...
