Converting cubic tons (i.e., volumes) to measures of weight presents difficulties because organic materials such as timber vary in density. Approximate volume conversions, based on a timber cubic ton of 40 cubic feet: 1 ton (40 cubic feet) = 1.133 cubic metres; 1 cubic metre = 0.883 cubic tons (35.32 cubic feet)
Log–log plot comparing the yield (in kilotonnes) and mass (in kilograms) of various nuclear weapons developed by the United States.. The explosive yield of a nuclear weapon is the amount of energy released such as blast, thermal, and nuclear radiation, when that particular nuclear weapon is detonated, usually expressed as a TNT equivalent (the standardized equivalent mass of trinitrotoluene ...
In surface mining, stripping ratio or strip ratio refers to the amount of waste (or overburden) that must be removed to release a given ore quantity. [1] [2] It is a number or ratio that express how much waste is mined per unit of ore.
The WABCO 3200 was a rare example of a tri-axle haul truck configuration A medium sized haul truck, the 214-short-ton (194 t; 191-long-ton) Caterpillar 789 [1]. Most haul trucks have a two-axle design, but two well-known models from the 1970s, the 350T Terex Titan and 235T WABCO 3200/B, had three axles.
Its large size (largest in the world of its type at the time of construction) created design challenges. [2]In order to create an economically feasible vessel of this size, the vessel must be designed with a high deadweight tonnage and a relatively high sailing speed to allow large quantities of rock, with densities ranging from 1.4–1.8 metric tons (1.4–1.8 long tons; 1.5–2.0 short tons ...
Decomposed granite is a kind of granite rock that is weathered to the point that the parent material readily fractures into smaller pieces of weaker rock. Further weathering yields material that easily crumbles into mixtures of gravel -sized particles known as grus that further may break down to produce a mixture of clay and silica sand or silt ...
Classes range from “R-20” (20 lbs) to “R-1500” (1,500 lbs) - see the table below. The standard also provides conversions to equivalent size using different shapes and considers specific gravities ranging from 2.60 to 2.75. The standard does not cover large armourstone employed for outer harbour structures such as breakwaters and revetments.
Mineral resource estimation is used to determine and define the ore tonnage and grade of a geological deposit, from the developed block model.There are different estimation methods used for different scenarios dependent upon the ore boundaries, geological deposit geometry, grade variability and the amount of time and money available.
