• Laboratory Evaluation of Pressure Differential-based Respirable Dust Detector Tube
  1/1/2000 - Peer reviewed journal articles
  Assessment of exposure to occupational dusts is a first step in reducing exposures to harmful dust concentrations. A new type of respirable dust sampler was developed and compared side-by-side to personal gravimetric samplers in the laboratory.
• A Passive Means to Detect Hot Trolley Insulators
  1/1/2000 - Peer reviewed journal articles
  NIOSH has devised a passive means to detect overheating insulators on direct current systems.
• Safety Framework for Programmable Electronics in Mining
  12/1/1999 - Peer reviewed journal articles
  Mining has one of the highest annual average fatality rates among major US industries. The US National Institute for Occupational Safety and Health (NIOSH), Pittsburgh Research Laboratory in Pittsburgh, PA is addressing the safety of this new technology.
• Computerized Accident Reconstruction and Training for Metal/Non-Metal Mines
  12/1/1999 - Peer reviewed journal articles
  NIOSH is developing computer programs that will be used to educate mine workers on the hazards of mining, as well as train miners in evacuation routes and evacuation procedures.
• Analysis of Pillar Design Practices and Techniques for U.S. Limestone Mines
  12/1/1999 - Peer reviewed journal articles
  As underground stone mining expands to deeper cover and more efficient methods are used, effective stone pillar design methods become more important. In this paper, 72 stone mine pillar designs are examined for factors affecting stability.
• Improved Seat Reduces Jarring/Jolting for Operators of Low-Coal Shuttle Cars
  12/1/1999 - Peer reviewed journal articles
  With input from underground shuttle-car operators, this study addressed a component of WBV that is germane to underground mining: high-energy impacts or shocks.
• Safer Mine Hoisting With Conveyance Position and Load Monitoring
  9/1/1999 - Peer reviewed journal articles
  A mine shaft is the lifeline to underground mines. Mine operators depend on safe, uninterrupted, and efficient movement of workers and materials. The shaft and hoisting system provides access to the network of openings used to recover the underground ...
• 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...
• Field Assessment of Control Techniques and Long-Term Dust Variability for Surface Coal Mine Rock Drills and Bulldozers
  9/1/1999 - Peer reviewed journal articles
  Airborne respirable dust surveys were conducted at six surface coal mines to investigate the effectiveness of dust control methods used on rotary rock drills and bulldozers.
• Ventilating the Box Cut of a Two-Pass 40-ft Extended Cut
  7/1/1999 - Peer reviewed journal articles
  Describes a NIOSH study of how much ventilation air reaches the end of a 40 foot box cut. Tests were run to determine how much ventilation air reaches the end of the box cut with the continuous miner at three locations in the 40-ft two-pass extended cut...
