Loose Density Of Blasted Rock At Quarry

rock factor (that depends on rock density, rock strength and jointing) A = ++0.06 RMD RDI HF( ) (3.6) The rock characterization factor A is calculated to correct the mean fragment size. It is made up of 3 factors which are the rock mass description (RMD), rock density influence (RDI) and the hardness factor (HF) [2]. 2.3.9

Blasting mechanics: Material properties and ... - Pit & Quarry

Apr 17, 2019 Today, in a majority of situations, the blast is now designed only considering the density of the rock because, generally, as the rock gets denser, it also gets stronger. For example, a sandstone has a lower density than a granite and, as such, will be blasted with a larger burden than a granite

test is 53.9 and the average density of the rock is 2.65 g/cm3, the estimated mean uniaxial compressive strength value of the quarry is 154 MPa.The quarry uses equal dimension for its burden and spacing. The burden and spacing values are either 1.5 m or 2 m for a given blast design.The quarry’s blasting patternsgivespowder

The Density of Common Rocks and Minerals - ThoughtCo

Jan 23, 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)

Density of Gravel, loose dry in 285 units of density

Gravel, loose dry weighs 1.522 gram per cubic centimeter or 1 522 kilogram per cubic meter, i.e. density of gravel, loose dry is equal to 1 522 kg/m . In Imperial or US customary measurement system, the density is equal to 95.0154 pound per cubic foot [lb/ft ], or 0.87977 ounce per cubic inch [oz/inch ]

Procedures for determining compacted Rockfill Lift

For example, a rock borrow material with typically 18 inch (0.45 m) square mesh maximum rock fragment sizes with occasional rock fragment sizes greater than 18 inch (0.45 m) could be placed in 24 inch (0.6 m) maximum loose lifts for test fill compaction by a 15 ton (static drum weight) vibratory roller

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/
