Coal mining - Coal mining - Choosing a mining method: The various methods of mining a coal seam can be classified under two headings, surface mining and underground mining. Surface and underground coal mining are broad activities that incorporate numerous variations in equipment and methods, and the choice of which method to use in extracting a coal seam depends on many technological, economic. Mine power trailing cables are subject to considerable abuse and are quite often damaged severely enough to require a repair splice. Although recently developed splice materials provide a splice.
Coal mining is the process of extracting coal from the ground. Coal is valued for its energy content and since the s, has been widely used to generate electricity. Steel and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production. In the United Kingdom and South Africa, a coal mine and its structures are a colliery, a coal mine is a 'pit', and. Flexible reeling and trailing cable repair services. In the repair of flexible reeling and trailing cable, Mine Cable Services employs factory-trained repair technicians and is approved to repair Pirelli Protolon cable. This approval includes the repair of Pirelli Protolon cable with fiber optic filaments.
Because coal mining operations use conveyor belts extensively to move materials, you must be able to count on your mining equipment to work efficiently without unscheduled downtime. Every time you have to stop production for unexpected problems like repairs or housekeeping, profitability drops. This program will discuss some of the more common types of electrical hazards that may be found in underground mines. While being of benefit to certified electricians as a review, this program deals with basic electrical safety and is intended for the general underground mining population.

For everything from shuttle cars, drills and loading machines, to roof bolters, longwall shearers, drag walls and shovels, Anaconda ® Brand lead-cured portable and trailing mining cables are engineered to exceed ICEA, CSA and MSHA compliances for use with a variety of mining equipment in severe applications where maximum safety and frequent relocation is necessary.
General Cable mining cables are manufactured in accordance with: † ICEA S Portable and Power Feeder Cables for Use in Mines and Similar Applications † CAN/CSA C No. 96 Portable Power Cables, and certified by Natural Resources Canada † CAN/CSA C.
Types of Flexible Cables in Mines: Flexible cables used in the electrical system of a mine fall into two main categories – trailing cables and pliable wire armour cables. (1) Trailing Cables: The majority of modern trailing cables have five cores—three power cores for the three phase a.c.

book technical support and logistical expertise. In and the Queensland Mines Inspectorate received ninety reports of damage to high voltage trailing cables supplying draglines (64 incidents) and electric overburden shovels (26 incidents). Incidents due to rocks falling from buckets and the spoil dumps rose from four in to ten in (eight of these occurred at draglines.
Mining cables are utilized in various types of mining applications and intended for long-term performance in the extremely harsh environment, while providing the greatest levels of safety and productivity. These cables offer excellent flexibility, torsion and drag resistance, in addition to exceptional electrical, temperature parameters.
MINE SERVICES. Electric Power. The majority of Australian coal mines have power supplied by another entity to a surface substation on site. Power is fed through switchgear to main feeder(s) to required locations around the surface and to underground, at most.

Future electrical safety research by NIOSH will continue to address issues and hazards that have been linked to many past electrical injuries, as well as potential hazards from new technology.
Examples include shock and burn hazards associated with switching equipment and cables, improved training, battery safety, and equipment permissibility. The Coal Mine Safety and Health Act expanded the Bureau of Mines’ research regarding electrical safety.
The act required the monitoring of ground conductor continuity to prevent electrocutions using a special device. s: The industry improved upon trailing cable splicing procedures and splice kits.
Research led to best practices. turers as was the case for the installation of cables in shafts and boreholes (Ilsley and Gleim ). At that time, several states had enacted laws governing mining equipment based upon the recommendations of the Bureau of Mines. It was only later, inthat a federal safety code for bituminous coal and lignite mines was enacted.
Underground Mine Cables a ustralian and new Zealand coal mines are some of the safest in the world. this safety record is built on strict controls and legislation to ensure that the cables for mining equipment and in particularly those used in hazardous areas are of particularly high quality.
The Prysmian Group’s elastomeric cables have been “field proven” in thousands of operations, and with continuous development, utilise the best features of cables offered around the world. In Australia, as elsewhere, there are many established guidelines governing manufacture of mining and industrial cables.
