• Evaluation of Seat Designs Relative to Transmitted Vehicle Vibration on Underground Mine Transport Vehicles
  10/1/2006 - Conference papers
  This study focused on reducing injury risk by improving seating on transport vehicles such as scoops, mantrips, personnel carriers, and rail-mounted locomotives.
• The Effects of Scaling Height and Scaling Bar Design on Applied Forces and Bilateral Muscle Activity of the Back and Shoulders
  10/1/2006 - Conference papers
  Hand scaling is a physically demanding job responsible for overexertion injuries in mining. This experiment studied rib scaling from an elevated bucket to examine force generation capabilities and electromyographic responses to a prying subtask.
• Coal Mine Safety Achievements in the USA and the Contribution of NIOSH Research
  9/1/2006 - Conference papers
  Discusses past NIOSH research that has helped to reduce hazards, accidents, and health issues in mining, as well as current NIOSH research priorities and the impact of the MINER Act of 2006.
• Explosion Temperatures of Metals and Other Elemental Dust Clouds
  8/1/2006 - Conference papers
  NIOSH conducted a study of the explosibility of various metals and other elemental dusts dispersed in air to aid in understanding dust cloud combustion and in evaluating the explosion hazards in the minerals and metals processing industries.
• Coal Mine Geology in the U.S. Coal Fields: a State-of-the-art
  8/1/2006 - Conference papers
  Describes the procedures and thought processes used by coal mine geologists when determining various mineability and reserve extraction feasibility issues. The paper also address underground geologic hazard mapping and prediction techniques.
• Load Capacity and Stiffness Characteristics of Screen Materials Used for Surface Control in Underground Coal Mines
  8/1/2006 - Conference papers
  NIOSH conducted an evaluation of screen materials commonly used in U.S. coal mines to determine their support characteristics and identify the parameters that could affect their performance with respect to controlling the fall of rock from the roof.
• Geology, Ground Control, and Mine Planning at Bowie Resources, Paonia, CO
  8/1/2006 - Conference papers
  Bowie Resources maintains one of the most pro-active ground control programs in the U.S. mining industry today. Everyone in the organization from the miners to top management is involved in ground control. The program is described in detail.
• Pillar Stability Issues Based on a Survey of Pillar Performance in Underground Limestone Mines
  8/1/2006 - Conference papers
  A survey of pillar conditions was carried out at 21 operating limestone mines that use the room-and-pillar method. Pillar instability is most likely caused by unfavorable geological structures in pillars with width to height ratios of less than 1.5.
• Twenty-four Conferences; More than One-hundred and Seventy Papers; Understanding Roof Bolt Selection and Design Still Remains Priceless
  8/1/2006 - Conference papers
  This retrospective paper discusses changes in bolt types and usage over the past 24 years, pointing out some of the biggest myths and hailing the most significant advances.
• Identifying Moisture Sensitive Roof Rocks in Coal Mines
  8/1/2006 - Conference papers
  NIOSH conducted wet/dry immersion cycling of clay-rich rocks, which provides an accurate, quick and inexpensive method for estimating the moisture sensitivity of mudrocks. With this information mine operators can begin to anticipate hazardous ground.
