pressure of air increases to twice 12 that at the surface. This was the sole reference to the pressure inside the Western Deep that the authors could find. The Western Deep is located at a latitude of 26°S at an elevation 13 of h = 1740 m. For T 0, the authors take
Prior to the Sago Mine disaster in 2006, mining regulations required seals to withstand a 140-kPa (20-psig) explosion pressure (30 CFR4 75.335(a)(2)). However, Program Information Bulletin No. P06-16 issued by MSHA on July 19, 2006 [McKinney 2006], requires seals to withstand a 345-kPa (50-psig) explosion pressure.

Equipment performance systems keep mining equipment operating at peak performance levels by monitoring temperature, pressure, RPM, velocity, power, acceleration, position, torque, and strain. Roof and shaft stability systems are used to warn of possible cave-in conditions by monitoring changing conditions, cracks, and load distribution.

Large quantities of water are used in mining operations for cooling machinery, dust suppression, cleaning, fire-fighting and drinking. ... Sometimes, where high quantities are required an additional high pressure line is run, without outlets, to a point closer to the working area before a pressure
A land mine is an explosive device concealed under or on the ground and designed to destroy or disable enemy targets, ranging from combatants to vehicles and tanks, as they pass over or near it. Such a device is typically detonated automatically by way of pressure when a target steps on it or drives over it, although other detonation mechanisms are also sometimes used.

Mining is the extraction (removal) of minerals and metals from earth. Manganese, tantalum, cassiterite, copper, tin, nickel, bauxite (aluminum ore), iron ore, gold, silver, and diamonds are just some examples of what is mined. ... They use a high pressure
