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 - Information CircularsThis report describes a study of operator movement relative to the motion of a roof bolting machine boom arm. This work was aimed at reducing the risk of injury to underground coal mine workers from moving machinery.
-
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.
-
1/1/2010 - Peer reviewed journal articlesThis study tests the ability of a new air nozzle system, located under the drill deck shroud, to improve the dust capture of the drill deck shroud.
-
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.
-
5/1/2009 - Peer reviewed journal articlesThis report describes research by NIOSH to reduce the noise exposures of jackleg drill operators and to prevent additional cases of noise induced hearing loss (NIHL) by developing and evaluating low-cost retrofit noise controls for equipment.
-
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.
-
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.
-
12/1/2008 - Peer reviewed journal articlesThis paper describes a recent research project initiated by NIOSH which identified improvement of the drill shroud design as one of its main objectives for reducing the exposure of surface miners to respirable dust.
