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.
-
1/1/2003 - Conference papersComputer human modeling was used to examine machine appendage speed. The objective was to determine the impact of roof bolter machine appendage speed on the likelihood of the operator coming in contact with the appendage.
