2/1/2007 - Peer reviewed journal articlesThis paper describes three mechanical methods - the mobile manipulator, the in-mine hoist, and a cable-handling system - developed by NIOSH to reduce injuries related to handling supplies or material, loading and unloading, and moving power cables.
9/1/2006 - Peer reviewed journal articlesThere are potential detrimental effects of capacitance charging currents during line-to-ground faults in mine power distribution systems. A representative mine power system is modeled, and simulations with faults at various locations are conducted.
Distributed Measurement of Conductor Temperatures in Mine Trailing Cables Using Fiber-Optic Technology3/1/1998 - Peer reviewed journal articlesMine trailing cables operated above safe thermal limits can cause premature insulation failure, increasing electrocution and fire hazards. This paper describes an approach to measuring temperatures within reeled cable under dynamic test conditions.
3/1/2001 - Peer reviewed journal articlesCoal miners often handle heavy electrical power cables, weighing up to 10 kg per meter. These cables are manually lifted and attached to the mine roof to prevent damage from mobile underground equipment.
