• MultiFit4: An Improved System for Insert-Type
  9/1/2010 - Peer reviewed journal articles
  This paper describes the results of initial testing of the NIOSH Multifit4 system that was designed to be used as a tool by qualified researchers to evaluate hearing protector training and fit interventions at worksites.
• Acoustic Assessment of Pneumatic and Electric Jackleg Drills used in the Mining Industry
  4/1/2010 - Conference papers
  This paper presents an acoustic assessment of pneumatic and electric jackleg drills involving Noise Source Identification (NSID), penetration rate measurements, operator’s cumulative noise dose measurements, and determination of sound power levels.
• Straight Line Walking and Path-Turn Identifying Algorithms for a Tracking Device Used in Underground Mines
  1/1/2010 - Conference papers
  This paper describes two algorithms that can provide greater accuracy for underground miner tracking systems.
• Algorithms to Identify Its Own and Surrounding Tunnels for an Underground Tracking Device
  1/1/2010 - Conference papers
  This paper introduces algorithms to locate miners with no need for external reference sensors. There are definitions of useful mathematical operations that can be performed on the node coordinates and includes a description of the algorithms.
• Evaluation of Sequential Extraction Procedures for Soluble and Insoluble Hexavalent Chromium Compounds in Workplace Air Samples
  2/1/2009 - Peer reviewed journal articles
  The results of this study by NIOSH have served to provide performance data in support of the procedures described in the international standard methods, for which such results were previously unavailable in the peer-reviewed literature.
• Exploration of Two Position Adjustment Methods for Underground Mine Tracking Systems
  1/1/2009 - Conference papers
  This paper introduces two position adjustment methods for mine tracking systems which use a coplanar node-path network mine model as the foundation for their development.
• A Case Study in Applied Social Marketing: Developing an Occupational Safety and Health Product
  12/1/2008 - Peer reviewed journal articles
  This case study provides an example of how social marketing was applied to meet the needs of business customers in the mining industry.
• The Application of Major Hazard Risk Assessment (MHRA) to Eliminate Multiple Fatality Occurrences in the U.S. Minerals Industry
  10/1/2008 - Information Circulars
  This NIOSH pilot project demonstrated that most US mines have the capability to successfully implement an MHRA. The basic requirement for a successful MHRA is the desire to become more proactive in reducing risks associated with catastrophic events.
• Work Practices to Manage Bump Prone Ground
  7/1/2008 - Conference papers
  This paper will review current and historic work practices used internationally to minimize the hazard to miners from mining in conditions which could produce a bump.
• Self-Contained Self-Rescuer Long Term Field Evaluation Tenth Phase Results
  6/1/2008 - Reports of Investigations
  This report is the last of 10 report phases begun in 1982 and presents findings regarding laboratory-tested SCSRs in the tenth phase of testing, from July 2004 to March 2006.
