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 paper presents an acoustic assessment of pneumatic and electric jackleg drills involving Noise Source Identification (NSID), penetration rate measurements, operator’s cumulative noise dose measurements, and determination of sound power levels.
-
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.
-
2/1/2009 - Conference papersThis paper presents the results of laboratory testing to determine if the installation of a horizontal air blocking shelf around the inside perimeter of a surface mining drill deck will improve dust capture.
