3/1/2012 - Technology NewsThis paper describes an engineering noise control that reduces roof bolting machine (RBM) operators’ exposure to noise in underground coal mines, thereby decreasing the risk of noise-induced hearing loss (NIHL) in RBM operators and nearby workers.
3/1/2011 - Peer reviewed journal articlesField tests confirm that an air-blocking shelf installed in the inside perimeter of a blasthole drill shroud substantially improves dust control. This modification reduced respirable dust by 66%–81% in the immediate vicinity of the shroud...
3/1/2001 - Conference papersAn analysis of roof bolting tasks was conducted at a mine to identify early warning signs of cumulative trauma. Health and safety risk factors were identified and recommendations to reduce cumulative trauma exposure were provided.
8/1/2000 - Conference papersRock drilling parameters including thrust, rotational speed, torque and velocity were examined to determine the ability to identify the strength of the rocks being drilled from the measured parameters.
Field Comparison of a Roof Bolter Dry Dust Collection System with an Original Designed Wet Collection System for Dust Control12/1/2020 - Peer reviewed journal articlesA study comparing dry dust collection with a wet dust collection at one coal mine location.
6/1/2020 - Peer reviewed journal articlesA report on the NIOSH-developed Saturn LED area light's ability to reduce glare that has typically been an issue for roof bolter operators.
1/9/2020 - Research projectsA project to develop durable noise controls that reduce the noise exposure of jumbo drill operators and facilitate the commercialization of the controls to make them available for all miners.
A Field Study of a Roof Bolter Canopy Air Curtain (2nd Generation) for Respirable Coal Mine Dust Control9/1/2019 - Peer reviewed journal articlesThis article describes NIOSH's testing of a 2nd generation roof bolter canopy air curtain (CAC) design at a Midwestern underground coal mine.
8/1/2019 - Peer reviewed journal articlesThis study focuses on the visibility of trip hazards within the interior working areas of the roof bolting machine for various lighting conditions that include the NIOSH-developed Saturn LED area luminaire.
11/8/2017 - Technology NewsRead the latest Technology News describing the NIOSH-developed Saturn area light, which significantly improves illumination for roof bolting machines.
