10/1/2005 - Conference papersThe focus of this research was to determine the noise exposures of heavy construction equipment operators while documenting the workers’ tasks, (i.e. hauling, moving, and/or pushing construction material).
-
10/1/2004 - Conference papersDescribes a method for assessing equipment jolting using a combination of "black boxes" called Shox Boxes and an onboard GPS system. The resulting configuration provides an objective assessment of jolting and a chance to determine its root causes.

6/1/2003 - Conference papersThis paper analyzes extensive noise and urethane durability testing on a Joy 14CM9 continuous miner's conveyor assembly, tail roller, and bottom plate conducted at NIOSH's Pittsburgh Research Laboratory facilities.
-
6/1/2003 - Conference papersThis paper identifies the most significant noise-radiating surfaces on a continuous miner tail section and examines the effects of three engineering noise controls.
-
10/1/1998 - Conference papersLike many experienced workers, remote control continuous miner operators perform their everyday jobs making choices and decisions that they may not consciously think about. To better understand what potential cues and feedback help to guide the operator...

5/1/1998 - Technology NewsThis Tech News reports on the evaluation of the air quantity reaching the face of a 40 foot box cut during a two-pass extended cut sequence.
-
11/1/1997 - Reports of InvestigationsThe results of laboratory, field, and open pit accuracy and performance testing of the Honeywell Ring Laser Gyro Inertial Navigation System, a navigation system designed to provide the heading and location of a remote controlled miner, are presented.
-
8/1/1997 - Hazards IDsA study was conducted examining the risk of silica dust exposure in mine workers exposed to continuous miners equipped with flooded bed scrubbers.
-
7/1/1997 - Technology NewsTo provide a safe, practical, cost-effective method for measuring coal rib thickness during highwall mining.
