The total amount of heat, in British thermal units per hour, that must be removed from the air by the cooling coils.
Industry:Mining
The total amount of heat, sensible and latent, which must be removed by the air in the working places.
Industry:Mining
The total amount of pressure required to force a liquid or grout into cracks, cavities, and pores in rocks or other substance.
Industry:Mining
The total amount of sensible and latent heat to be removed from a space to maintain desired conditions. For mines in operation, it is possible to measure the actual amount of heat generated in underground openings by observing temperature changes in a known weight flow rate of mine air. For projected mines and extensions of operating mines, the amount of heat produced must be calculated, knowing which of the sources of underground heat is operative.
Industry:Mining
The total amount of solid material in grams contained in 1 kg of water when all the carbonate has been converted to oxide, the bromine and iodine have been replaced by chlorine, and all organic matter has been completely oxidized. Expressed as grams per kilogram of water or parts per thousand.
Industry:Mining
The total area of a given length of airway; i.e., the area of top, bottom, and sides added together, or the perimeter multiplied by the length.
Industry:Mining
The total energy at any section in a moving fluid consists of the sum of the internal static, velocity, and potential energies at that section.
Industry:Mining
The total force per unit area acting within a mass of soil. It is the sum of the neutral and effective stresses.
Industry:Mining
The total length of surface in a channel or pipe that is in actual contact with water.
Industry:Mining
