• Characteristics of the Top Five Most Frequent Injuries in United States Mining Operations, 2003-2007
  1/1/2010 - Peer reviewed journal articles
  This report describes an alternative method of analyzing and presenting MSHA data for the purpose of identifying high-cost, high-severity injuries and illnesses.
• Passive Mine Blast Attenuators Constructed of Rock Rubble for Protecting Ventilation Seals
  1/1/2010 - Peer reviewed journal articles
  This paper discusses some concepts and preliminary test results for a Passive Mine Blast Attenuator (PMBA) that can provide a useful alternative to increasingly larger and stronger stand-alone mine seals.
• Update on Refuge Alternatives: Research, Recommendations, and Underground Deployment
  12/1/2009 - Peer reviewed journal articles
  This document highlights NIOSH's research and recommendations concerning refuge alternatives, survivability evaluations of refuge chambers, and presents a brief review of the current deployment of refuge chambers in underground coal mines in the U.S.
• Numerical Study on Spontaneous Combustion of Coal in U.S. Longwall Gob Areas
  11/1/2009 - Conference papers
  In this paper, computational fluid dynamics (CFD) modeling results for both bleeder and bleederless ventilation systems are presented and the difference between two systems is discussed.
• Results of In-Mine Research in Support of the Investigation of the Sago Mine Explosion
  9/1/2009 - Reports of Investigations
  The information in this report was used by MSHA and WVOMHS&T as supporting data in their analyses and investigative reports of the Sago Mine explosion.
• Noise Source Identification on a Horizontal Vibrating Screen
  7/1/2009 - Peer reviewed journal articles
  This paper presents the results of a NIOSH study in collaboration with Acoustical and Vibrations Engineering Consultants Inc. (AVEC) to determine the dominant noise sources on a vibrating screen machine at low frequencies, i.e., 250 to 1,000 Hz.
• Development of a Taxonomy for Indexing Web-based Mining Safety and Health Research
  11/1/2008 - Conference papers
  This paper discusses the development of a thesaurus of mining-related terms. This thesaurus will be used to index NIOSH Mining web site content to facilitate searching that content.
• Guidelines for Permitting, Construction, and Monitoring of Retention Bulkheads in Underground Coal Mines
  6/1/2008 - Information Circulars, Safety guidelines, tips, and checklists
  The guidelines in this report are to be used as a tool to identify areas or conditions that could impact the long-term stability of an underground fluid retention system and to give direction in addressing these situations.
• Performance of a Polyurethane Core Seal Tested in a Hydrostatic Chamber
  5/1/2008 - Reports of Investigations
  This paper presents the results of the full-scale test of a composite polyurethane-aggregate seal in a hydrostatic chamber conducted by NIOSH, and provides an analysis of those results in terms of the structural behavior of the seal.
• Identification of Noise Sources on Longwall Panels Using Multiple Time-Synchronized Dosimeters
  12/1/2007 - Peer reviewed journal articles
  This paper describes research designed to develop guidelines and test procedures for identifying all noise sources that are major contributors to the underground noise exposure of longwall coal mining system workers.
