• Application of Prevention through Design for Hearing Loss in the Mining Industry
  2/1/2008 - Peer reviewed journal articles
  This paper describes the quiet-by-design approach of a noise control that reduced exposures of continuous mining machine operators by 3dB(A) using the four functional areas of Prevention through Design - Practice, Policy, Research, and Education.
• In-Cab Noise Reduction on an Air-Rotary Drill Rig
  5/1/2007 - Peer reviewed journal articles
  This paper summarizes a NIOSH investigation of engineering noise controls to reduce sound levels in cabs on air-rotary drill rigs. Results revealed that some drillers are exposed to A-weighted sound levels exceeding 85 dB even though a cab is used.
• Assessment and Evaluation of Noise Controls on Roof Bolting Equipment and a Method for Predicting Sound Pressure Levels in Underground Coal Mining
  1/1/2006 - Theses/Dissertations
  This paper describes a research program implemented to measure sound power levels radiated by a roof bolting machine during differing drilling configurations and utilizing differing types of drilling methods in high compressive strength rock media.
• Evaluation of Engineering Noise Controls for a Continuous Miner Conveyer System
  6/1/2003 - Conference papers
  This paper analyzes extensive noise and urethane durability testing on a Joy 14CM9 continuous miner's conveyor assembly, tail roller, and bottom plate conducted at NIOSH's Pittsburgh Research Laboratory facilities.
• The Consequences of 'Leaky' Enclosures
  1/1/2002 - Peer reviewed journal articles
  Discusses design criteria for making a proper acoustical enclosure where a machine operator can safely and effectively work.
• EM Rescue (Location) System for Deep Mines: Phase II - Build and Test Breadboard Equipment
  10/1/1984 - Contract reports
  The purpose of this program is to extend electromagnetic (EM) techniques for use in locating miners trapped in mines as deep as 1000 m.
