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.
-
7/1/2008 - Peer reviewed journal articlesThis paper presents the results of NIOSH laboratory and field tests to evaluate the effectiveness of dust collector bags for reducing dust liberation and operator exposure from a roof bolter's dust collection system.
-
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.
-
10/1/2005 - Peer reviewed journal articlesNIOSH researchers successfully developed a computer model that generates contact data by means of simulation while exercising the model with several variables associated with the machine and its operator.
-
1/1/2005 - Peer reviewed journal articlesThe noise-control treatments most commonly observed on drills and bolters during this study were evaluated on machines at underground metal mines to determine the amount of noise reduction achieved by each control.
