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.
-
9/1/2008 - Peer reviewed journal articlesThe objectives of this study by NIOSH were to assess driver whole-body vibration (WBV) exposures and recommend interventions to reduce the risk of back-related injuries, particularly relative to vehicle jarring/jolting.
-
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.
-
5/1/2007 - Peer reviewed journal articlesThis 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.
-
1/1/2006 - Peer reviewed journal articlesNIOSH initiated a study of a roof bolter to reduce noise exposure to mine roof bolter operators. When drilling into granite, it was found that wet drilling generated lower sound power levels and performed better than vacuum drilling.
-
12/1/2005 - Peer reviewed journal articlesThis publication describes worker noise exposure surveys in coal mines and coal preparation plants, revealing that worker dosimetry, time-motion studies, and equipment noise profiling are important for effective use of administrative controls.
-
1/1/2005 - Peer reviewed journal articlesThis paper reports on a cooperative study on vibrating screen noise conducted at a coal preparation plant. Rubber isolators were found to reduce sound levels by 1 dB and amped side plates reduced vibration levels on the screen sides by 1 to 7 dB(A).
-
1/1/2002 - Peer reviewed journal articlesDiscusses design criteria for making a proper acoustical enclosure where a machine operator can safely and effectively work.
