• Multiple-Seam Mining in the United States: Design Based on Case Histories
  5/1/2007 - Information Circulars
  The goal of this study is to help identify the location and likely severity of multiple-seam interactions. Mine planners can use this information to adjust the ground support, pillar design, or mine layout to minimize the hazard.
• Multiple-Seam Mining in the United States: Background
  5/1/2007 - Information Circulars
  For the past several years, NIOSH has been conducting research to develop better techniques for predicting the location and severity of multiple-seam interactions. This paper presents the background to that study.
• Implementation of an Ergonomics Process at a US Surface Coal Mine
  2/1/2007 - Peer reviewed journal articles
  In 2000, NIOSH initiated a long-term project to demonstrate how to implement an ergonomics process to identify and reduce exposures to ergonomic risk factors found in mining. This paper discusses how a coal mine implemented an ergonomics program.
• Water and Slurry Bulkheads in Underground Coal Mines: Design, Monitoring, and Safety Concerns
  12/1/2006 - Peer reviewed journal articles
  This paper presents the results of NIOSH research to identify state-of-the-art bulkhead designs, including design criteria, leakage monitoring systems, and emergency warning systems.
• Underground Evaluation of Coated Flight Bars for a Continuous Mining Machine
  12/1/2006 - Conference papers
  A highly durable polyurethane coating has been developed for chain flights to decrease noise from metal-on-metal impacts. This paper evaluates this engineering noise control in reducing the noise exposure of continuous mining machine operators.
• 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.
• Managing Excess Gas Emissions Associated with Coal Mine Geologic Features
  6/1/2006 - Book chapters, Information Circulars
  This chapter summarizes how certain geologic features may be associated with unexpected increases in gas emissions during coal mining. These unexpected emissions have the potential to create explosive conditions in the underground workplace. Also discu...
• Numerical Modeling Procedures for Practical Coal Mine Design
  6/1/2006 - Conference papers
  A method is presented for creating realistic numerical models for practical coal mine ground control. This procedure enables realistic comparisons of the effectiveness of alternative rock support systems.
• 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.
• Technical Development of the Coal Dust Explosibility Meter
  1/1/2006 - Conference papers
  NIOSH's Office of Mine Safety and Health Research, in collaboration with MSHA Technical Support, has devised a prototype handheld device, Coal Dust Explosibitlity Meter (CDEM), to assess the potential explosibility of a coal and rock dust mixture.
