• Shock Reduction for Low-Coal Shuttle Car Operators Using Viscoelastic Seating Foam
  3/1/1998 - Conference papers
  The prolonged exposure of equipment operators to shock and whole-body vibration (WBV) is linked to cumulative back, neck, and abdominal disorders.
• Injury Analysis of Pennsylvania Small Surface Coal Mines
  3/1/1998 - Conference papers
  This paper is a descriptive analysis of injuries and fatalities at small surface bituminous coal mining companies in Pennsylvania.
• Water Mist Extinguishment of Pool Fires: A Parametric Approach
  3/1/1998 - Conference papers
  This paper describes a relatively simple indirect model for the parametric water injection process to extinguish diesel fuel fires in underground mine diesel refueling areas.
• Work Principle for Predicting Explosive Toxic Fumes
  2/1/1998 - Conference papers
  Research on applying the work principle to the non-ideal conditions of mining explosives to determine toxic fume production.
• The Calculated Risk of Experiencing a Lightning Caused Unplanned Detonation
  2/1/1998 - Conference papers
  This paper presents data and theorem to calculate the risk of experiencing undesirable lightning related events while blasting or while engaged in other lightning sensitive activities. The paper provides an overview of lightning hazards in blasting oper...
• Physical Strength Assessment in Ergonomics
  1/1/1998 - Conference papers
  This publication concerns human physical strength testing. Its purpose is not to recommend any particular type of testing, but rather to describe the types of testing available and their uses.
• International Experience with Longwall Mining into Pre-Driven Rooms
  1/1/1998 - Conference papers
  Unusual circumstances sometimes require a longwall retreat into/through a previously driven room, with the potential for failures and roof fall hazards. To determine the failure factors, NIOSH compiled an international database of 130 case histories.
• Investigation of Ampacity Derating Factors for Shuttle Cars Using Fiber Optics Technology
  10/1/1997 - Conference papers
  A method is described to determine dynamically the conductor temperature of reeled shuttle car cables using fiber optics technology.
• Safety Issues and the Use of Software-Controlled Equipment in the Mining Industry
  10/1/1997 - Conference papers
  This paper describes an effort initiated by the National Institute for Occupational Safety and Health (NIOSH) to identify the safety issues related to the use of processor-controlled equipment in mining.
• Biomechanical Modeling of Asymmetric Lifting Tasks in Constrained Lifting Postures
  10/1/1997 - Conference papers
  Twelve subjects participated in an investigation of the biomechanical stresses of asymmetric lifting in stooped and kneeling postures. Three factors were manipulated in this study: posture (stooped or kneeling), height of lift (35 or 70 cm), and weight ...
