• Instrumentation for Diesel Particulate Matter Emissions Research
  6/1/2006 - Conference papers
  The results of a series of tests in an underground mine were used to evaluate several measurement methods that are currently used to characterize particulate matter emitted by diesel-powered equipment. This paper presents an overview of these techniques...
• A New Method to Clean Dust from Soiled Work Clothes
  6/1/2006 - Conference papers
  Dust from worker's clothes has been shown to be a problematic source of personal dust exposure. A recently completed effort between NIOSH and Unimin Corp. has resulted in a quick and effective way to clean worker clothing. Field testing indicated that t...
• Novel Stopping Designs for Large-Opening Metal/Nonmetal Mines
  6/1/2006 - Conference papers
  The Super Stopping is designed as a long-term permanent stopping for use in the main entries of the mine, while the EZ-Up Curtain Stopping, although very durable, is designed more for portability and ease of installation. This paper describes the design...
• An Integrated Approach for Managing Diesel Emission Controls for Underground Metal Mines
  6/1/2006 - Conference papers
  Recent NIOSH experience suggests that more attention may be needed in managing the issues associated with diesel emissions and their control.
• Development of New Protocols to Evaluate the Transverse Loading of Mine Ventilation Stoppings
  6/1/2006 - Conference papers
  A new protocol based on rigid arch loading of the structure is proposed to determine the true transverse load capacity of block stoppings. Tests show that load capability depends on the block's physical properties and the wall's geometric properties.
• CO Dispersion from a Coal Fire in a Mine Entry
  6/1/2006 - Conference papers
  Five mine fire experiments were conducted in a 2.08-m-high, 2.90-m-wide ventilated mine entry in NIOSH's Safety Research Coal Mine to determine the effect of the dispersion of carbon monoxide (CO) on mine fire detection.
• DEEP Project on Evaluation of Diesel Particulate Filters at Inco's Stobie Mine
  6/1/2006 - Conference papers
  The objective of the Diesel Emissions Evaluation Program (DEEP)-sponsored project at Inco Ltd.'s Stobie Mine was to conduct a long-term field evaluation of diesel particulate filter (DPF) systems available to the underground mining industry. Some of the...
• Emerging Technologies Control Respirable Dust Exposures for Continuous Mining and Roof Bolting Personnel
  6/1/2006 - Conference papers
  This paper discusses NIOSH studies evaluating the impacts of emerging technologies that may reduce dust exposures for continuous mining and roof bolting personnel. These technologies include use of a wet-head cutting drum on a continuous mining machine,...
• Determining the Root Causes of Flame Cutting and Welding Fires in Underground U.S. Coal Mines
  6/1/2006 - Conference papers
  MSHA's reports and mining database were analyzed, and interviews and observations with mine workers and welders were conducted to determine the root causes of coal mine fires and explosions caused by flame cutting and welding operations.
• Musculoskeletal Symptoms Among Operators of Heavy Mobile Equipment
  6/1/2006 - Conference papers, NIOSH/USBM numbered publications
  The purpose of this study was to assess the adequacy of the cab design and to determine the percentage of musculoskeletal symptoms among operators of mobile equipment used in mining and construction.
