5/1/2009 - Peer reviewed journal articlesThis report describes research by NIOSH to reduce the noise exposures of jackleg drill operators and to prevent additional cases of noise induced hearing loss (NIHL) by developing and evaluating low-cost retrofit noise controls for equipment.
-
1/1/2009 - Peer reviewed journal articlesThis paper describes NIOSH research to evaluate noise generated by a roof bolting machine and its components. Results are given for two engineering controls for the roof bolting machine: a bit isolator and a drill chuck isolator.
-
3/1/2008 - Peer reviewed journal articlesThis paper presents research examining noise on dredges used in several surface mine sand and gravel operations and in the processing facilities.
-
3/1/2008 - Peer reviewed journal articlesThis study, conducted as part of a project to evaluate a new type of noise exposure monitoring paradigm, showed that the effects of dosimeter microphone placement in a diffuse field were found to be minor for most of the test microphones/locations.
-
12/1/2007 - Peer reviewed journal articlesThis 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.
-
12/1/2007 - Peer reviewed journal articlesThis 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.
-
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 - 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.
-
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.
