• Measuring Mining Safety with Injury Statistics: Lost workdays as Indicators of Risk
  12/1/2007 - Peer reviewed journal articles
  This paper describes an alternative measure of risk in mining using a beta distribution to model the losses and to compare underground coal mining to underground metal/nonmetal mining from 2000 to 2004.
• Practical Application of a Partial Cab to Reduce the A-Weighted Sound Level at the Operator's Station on Surface Drill Rigs
  12/1/2007 - Peer reviewed journal articles
  This paper discusses the results of a collaboration with a local drilling company to design and install a partial cab between the operator and the drill steel in an effort to reduce the sound level at the operator station of a surface drill rig.
• 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.
• Evaluation of Deep-Seated Crib Block Fires and Direct-Application Fire Suppression Agents
  12/1/2007 - Peer reviewed journal articles
  NIOSH and MSHA are conducting research to test, evaluate, improve, or modify coal mine fire-fighting methodologies through large-scale wood crib fire tests, in which products of combustion can be measured and observations can be assessed.
• Back Injury Control Measures for Manual Lifting and Seat Design
  12/1/2007 - Peer reviewed journal articles
  This article discusses research results of studies that shed light on possible mechanisms through which low back injuries may occur and how this knowledge can be leveraged to reduce the risk of low back pain.
• Noise and Hearing Protection: Development of Two Training Exercises for Drillers
  11/1/2007 - Peer reviewed journal articles
  This article reviews the development and evaluation of two training exercises developed to inform drillers about noise, hearing loss and proper use of hearing protection, and discusses their use and availability.
