IR Keeps West Virginia Coal Miners Safe
When all safety procedures are followed, coal mining is a very safe industry. Infrared testing is used to monitor the direct current trolley systems that power transportation vehicles. The trolley system can extend for 20 to 30 miles underground, and consists of a positive or negatively charged
Open Cut Mine Monitors Water Quality
An open cut coal mine having a high salinity of water runoff required monitoring the quality of water in several retaining dams. The water can only be released into the local river system when it is of sufficient quality to have no effect on the irrigation of the surrounding farming district.
The Evolution of Gas Protection
to the world of gas detection, single and multi-gas monitors evolved. The first electronic single gas monitors were basic at best. Designed for the coal industry to sniff out methane, these monitors utilised analogue readouts to indicate the presence of gas. Most monitors today offer considerably more
Confined Spaces and Gas Detection
. Is not designed for continuous employee occupancy. A few examples of confined spaces could be underground vaults in the telecommunications industry, aeronautical fuel tanks, sewers, silos, or coal mines.
Bulk Material Combustion Warning Systems (.pdf)
Many bulk materials, such as coal and organic wastes, are stored as large piles in open yards where air and moisture promote decomposition and exothermic reactions that raise the pile's temperature. Since self-ignition usually starts within the pile's lower layers, a full-blown fire can develop
Examining the Root Causes of Gearbox Failure Leads to Longer Life
Coal Age October, 2002 -- When equipment fails, often the biggest concern is how to get the equipment running again. Equally important, however, is discovering why the equipment failed and how such a failure can be prevented. Preventive maintenance is defined as the regular performance of equipment
