11/1/2007 - Peer reviewed journal articlesThis 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.
-
11/1/2007 - Conference papersThis paper details laboratory noise testing results of a continuous mining machine conveyor system which uses a coating for the tail roller designed to help bring the continuous mining machine into compliance with federal noise regulations.
-
11/1/2007 - Peer reviewed journal articlesThis paper presents a method using a ray-tracing technique to determine absorption coefficients for underground mines. Absorption coefficients are determined and presented for octave bands from 63 Hz to 8 kHz.
-
10/1/2007 - Conference papersThis paper evaluates the duty cycle of a typical roof bolting machine operation at two coal mines. The results provide insight into which portion of the operators’ duty cycle is the most prominent contributor to noise exposure.
-
10/1/2007 - Conference papersThis paper provides a method for predicting sound pressure levels at the operator’s position of a roof bolting machine in an underground coal mine using sound power levels determined in the laboratory.
-
10/1/2007 - Conference papersThis paper discusses the methods NIOSH used to identify noise sources on a roof bolting machine while drilling.
-
8/1/2007 - Peer reviewed journal articlesNIOSH completed a survey of equipment sound levels and worker noise exposures in the mining industry. The findings identify the equipment and machinery likely to cause worker overexposures and the workers found to be experiencing overexposures.
-
7/1/2007 - Peer reviewed journal articlesThis research determined noise exposures of equipment operators while documenting worker task. The types of equipment studied included asphalt pavers, backhoes, bulldozers, compaction equipment, excavators, haul trucks, and wheeled loaders.
-
1/1/2007 - Peer reviewed journal articlesNoise surveys were conducted in eight coal preparation plants. Results indicate that only workers who routinely spend a significant portion of their shift in the plants (away from the control rooms) are susceptible to overexposure from noise.
-
1/1/2007 - Peer reviewed journal articlesThis study examines the patterns and trends in noise exposure documented in data collected by Mine Safety and Health Administration inspectors at U.S. coal mines from 1987 through 2004.
