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.
-
6/1/2010 - Conference papersThis study examined the potential for coal mine roof bolter dust to be a source of a worker's exposure to respirable quartz.
-
4/1/2010 - Conference papersThis article presents the most significant findings from NIOSH research to develop noise controls that reduce the sound at the operator’s position of mining machinery.
-
4/1/2010 - Conference papersNIOSH conducted research to reduce the noise emission of various underground coal-mining equipment and developed a suite of controls to reduce drilling noise.
-
4/1/2010 - Conference papersThe paper documents NIOSH research to date of a damped drill steel on a roof bolting machine.
-
2/1/2010 - Conference papersNIOSH conducted a series of laboratory tests using a roof bolting machine to assess the respirable dust capture ability of a water exhaust conditioner as compared to the standard exhaust muffler.
-
11/1/2009 - Conference papersNIOSH is developing bit and chuck isolators to reduce vibration, and thus noise radiation of the drill steel, with the longer-term goal of reducing roof bolting machine operator noise exposure.
-
7/1/2008 - Conference papersThis paper describes and evaluates an engineering noise control for the roof bolting machine, namely the collapsible drill steel enclosure.
-
10/1/2007 - Conference papersThis paper evaluates the duty cycle of a typical roof bolting machine operation at two coal mines. The results provide insight into which portion of the operators’ duty cycle is the most prominent contributor to noise exposure.
