Advantages of electrical equipment needed for mines

naval mine a naval mine is a selfcontained explosive device placed in water to damage or destroy surface ships or submarines.unlike depth charges, mines are deposited and left to wait until they are triggered by the approach of, or contact with, any vessel.naval mines can be used offensively, to hamper enemy shipping movements or lock vessels into a harbour; or defensively, to protect friendly vesselsu.s. bureau of mines/niosh mining electrical safetyelectrical equipment used in potentially methane laden atmospheres must be housed in explosion proof (x/p) enclosures or be of intrinsicallysafe design, so as to have insuficient energy, under normal or faulted conditions, to ignite a methane air mixture.file size 1mbidentification, management, and proper disposal of pcbelectrical equipment and as coolants in motors in continuous miners and loaders in the mining industry. a common misperception is that because the regulations banned the manufacture of pcbs in 79, pcbcontaining electrical equipment is no longer in use. the regulations,common types of mining equipment used in the miningmining in nevadatypes of mining and their respective equipment10 types of heavy equipment used in miningnevada's mining industry is the biggest export sector in the state. precious minerals such as g, copper, and silver are wellknown materials mined. however, the state also extracts many other goods from the earth, including minerals used for both construction work and consumer goods. products mined for construction work include gravel, sand, gypsum, and limestone. these goods contribute to the building sites for erecting structures and infrastructure components required for modern living. consumers alselectrical equipment and power supply systems for minesjan 01, 90· therefore, protection against electricshock hazards must be designed in such a way that no danger to mine personnel can come from such faults in the system. 2 1.2 reliability of supply electrical equipment and power supply systems for mines the continuous and reliable supply of electric power is very important for all mining operations, particularly those in which power failureschecklist overview of regulations either frequentlyelectrical loading, hauling and dumping machinery and equipment personal protection and ppe required safety policies 56.009 emergencies person in charge of mine competent person designated by the mine operator shall be in attendance to take charge in case of an emergencycolorado of mines home colorado of minesthese tools are helping orediggers stay safe while sticking together. colorado of mines is a public research university focused on science and engineering, where students and faculty together address the great challenges society faces todayparticularly those related to
