• Surface Haulage Truck Research
  9/1/1999 - Peer reviewed journal articles
  NIOSH studies have focused on off-the-shelf technologies that would enable mine haulage truck drivers to "see" objects and people behind and to the side of a moving vehicle. This paper discusses two types of systems currently available: proximity warni...
• Tying Acceleration and GPS Location Information Together To Create a Mine Management Tool
  3/1/1999 - Conference papers
  Accelerometers and pressure transducers mounted in suspension components can be used to monitor the ride of haulage trucks. When information from a Global Positioning System is recorded at the same time as shock pressures or acceleration date, then the...
• Dynamic Temperature Measurement of Overheated Shuttle Car Trailing Cables in Underground Coal Mines
  1/1/1999 - Peer reviewed journal articles
  A method is described to measure the conductor temperature of mine trailing cables during normal operation. The temperature is measured using an optical fiber located in the center of the metallic conductors.
• Shock Reduction for Low-Coal Shuttle Car Operators Using Viscoelastic Seating Foam
  3/1/1998 - Conference papers
  The prolonged exposure of equipment operators to shock and whole-body vibration (WBV) is linked to cumulative back, neck, and abdominal disorders.
• Technology News 468 - Tests of Doppler Radar Technology for Haulage Truck Backup Alarms
  12/1/1997 - Technology News
  Current innovations in Doppler radar technology have led to suggestions by several institutions and manufacturers that new backup alarm systems are available that can replace or augment warning systems for backing operations on large haulage vehicles.
• Investigation of Ampacity Derating Factors for Shuttle Cars Using Fiber Optics Technology
  10/1/1997 - Conference papers
  A method is described to determine dynamically the conductor temperature of reeled shuttle car cables using fiber optics technology.
• Ergonomic Seat With Viscoelastic Foam Reduces Shock on Underground Mobile Equipment
  6/1/1997 - Conference papers
  This paper describes the underground mine trials and the testing done to evaluate properties of the viscoelastic foams. The paper also discusses the development of an analytical model using the data from underground trials and the foam testing.
• Technology News 459 - Ergonomic Seat Reduces Shock for Low-Seam Shuttle Car Operators
  5/1/1997 - Technology News
  The lack of sufficient vertical clearance in some underground mines is an impediment to providing adequate shock isolation systems on mine equipment seats.
• Safety Analysis of Surface Haulage Accidents
  1/1/1996 - Conference papers
  Report on research analyzing single and multiple causes of surface haulage accidents.
• Transverse-Mounted End-Cab Design for Low-Coal Shuttle Cars
  1/1/1993 - Reports of Investigations
  A prototype end-cab shuttle car (SC) design has been developed to improve protection and address ergonomic concerns of the SC operator in low coal mines. This report discusses research to modify a used 21SC JOY SC, retrofit the SC with the Bureau-devel...
