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 wire mounted near the roof on insulators. The rail (track) is the return. These systems power rail jeeps and locomotives that transport men and supplies to working sections of the underground. Trolley insulators are approximately 10 feet apart and insulate the trolley wire from either the roof or ground. If these insulators short, they can heat the roof and cause either a fire or a cave-in. With infrared testing, we can see bad insulators and loose connections on the track and rectifiers before they present a danger. An underground mine is similar to a small city. It takes electrical power, water, air ventilation and a transportation system to provide a safe working environment.
