A large dragline system used in the open pit mining industry costs approximately US$50–100 million. A typical bucket has a volume ranging from 40 to 80 cubic yards (30 to 60 cubic metres), though extremely large buckets have ranged up to 220 cubic yards (168 cubic meters). [12] The length of the boom ranges from 45 to 100 metres (148 to 328 ft).
Mud weight. In the oil industry, mud weight is the density of the drilling fluid and is normally measured in pounds per gallon (lb/gal) (ppg) or pound cubic feet (pcf) . [1] In the field it is measured using a mud scale or mud balance. Mud can weigh up to 22 or 23 ppg. A gallon of water typically weighs 8.33 pounds (or 7.48 ppg). In ...
The soil bulk density of cultivated loam is about 1.1 to 1.4 g/cm 3 (for comparison water is 1.0 g/cm 3). [48] Contrary to particle density, soil bulk density is highly variable for a given soil, with a strong causal relationship with soil biological activity and management strategies. [ 49 ]
The yard (symbol: yd) [3][4] is an English unit of length in both the British imperial and US customary systems of measurement equalling 3 feet or 36 inches. Since 1959 it has been by international agreement standardized as exactly 0.9144 meter. A distance of 1,760 yards is equal to 1 mile.
Big Brutus is the centerpiece of a mining museum in West Mineral, Kansas, United States, where it was used in coal strip mining operations. The shovel was designed to dig from 20 to 69 feet (6.1 to 21.0 m) [ 1 ] down to unearth relatively shallow coal seams, which would then be mined with smaller equipment.
The informal public imperial measurement standards erected at the Royal Observatory, Greenwich, London, in the 19th century: 1 British yard, 2 feet, 1 foot, 6 inches, and 3 inches. The inexact monument was designed to permit rods of the correct measure to fit snugly into its pins at an ambient temperature of 62°F (16 2 ⁄ 3 °C).
0.7645549 m 3. Imperial and US customary. 27 ft 3. A cubic yard (symbol yd3) [1] is an Imperial / U.S. customary (non- SI non- metric) unit of volume, used in Canada and the United States. It is defined as the volume of a cube with sides of 1 yard (3 feet, 36 inches, 0.9144 meters) in length.
A full bushel is represented by a basket in the lower right. A bushel (abbreviation: bsh. or bu.) is an imperial and US customary unit of volume based upon an earlier measure of dry capacity. The old bushel is equal to 2 kennings (obsolete), 4 pecks, or 8 dry gallons, and was used mostly for agricultural products, such as wheat.
