    Bulking is the phenomenon of volume increase that occurs when solid rock is broken (Nelson, 1965). The volume of broken rock may increase relative to the original volume because the broken rock pieces typically do not fit together perfectly, which results in an increase in void space included with the rock solids. Depending on its initial state of

    BLASTING: One of the most common complaints associated with a quarry operation is the blasting. When an explosive is detonated enormous amounts of energy are released. While some of the energy of a blast works to displace rock from the quarry face, the remaining energy is released as vibrations through and along the surface of the earth and

    The fragmentation of rock is fundamental to mining. It is the first preparatory stage in the extraction process – making rock small enough and loose enough to be efficiently excavated. But this simple statement underestimates how important this activity is for the whole mining operation. By optimising rock fragmentation by blasting, you can

    Jan 22, 2020 The densities of rocks and minerals are normally expressed as specific gravity, which is the density of the rock relative to the density of water. This isn't as complex as you may think because water's density is 1 gram per cubic centimeter or 1 g/cm 3. Therefore, these numbers translate directly to g/cm 3, or tonnes per cubic meter (t/m 3)

    As specific gravity is just a comparison, it can be applied across any units. The density of pure water is also 62.4 lbs/cu.ft (pounds per cubic foot) and if we know that ammonium nitrate has a sg of 0.73 then we can calculate that its density is 0.73 x 62.4 = 45.552 lbs/cu.ft. Note, kg/cu.m divided by 16.02 = lbs/
