10/1/2003 - Peer reviewed journal articlesThis study evaluated two training techniques for educating young children about noise and hearing loss.
-
8/1/2003 - Conference papersTo measure the loading behavior of friction bolts, NIOSH researchers installed strain gauges on the interior of friction bolts and developed a miniature data acquisition system (MIDAS) that fits inside the hollow portion of the friction bolt.
-
6/1/2003 - Conference papersUsing hollow inclusion stress cells, researchers obtained two in situ stress measurements from the face of two footwall lateral drifts at the Stillwater Mine near Nye, MT.
-
11/1/2002 - Conference papersThis study of the Chestnut Ridge Anticline found that high levels of horizontal stress are to be expected and that local geologic and topographic structures can alter the magnitude and possibly the orientation of the horizontal stress field.
-
8/1/2002 - Conference papersStudies have identified a number of factors for evaluating a pillar extraction plan. This paper discusses each of the factors, presents relevant accident statistics, and shows how the risk factors can be combined to estimate the overall hazard.
-
7/1/2002 - Conference papersThe investigation reported here is an initial study of the stability of the first of the proposed chambers at the Homestake Mine in Lead, SD.
-
2/1/2002 - Conference papersSixty years of rockbursting in the Coeur d'Alene district has taught painful lessons and led to practical advances in controlling rockburst hazards. This paper summarizes those lessons, concentrating on practical measures to reduce hazards.
-
8/1/2001 - Conference papersThe location and time of 2,007 microseismic emissions from a limestone mine were compared with mine face development and mine layout characteristics. The occurrence of roof failure zones appears to be associated with mine plan characteristics.
-
7/1/2001 - Reports of InvestigationsBecause backfill has occasionally collapsed into an active working area, posing a hazard to miners, engineers installed instruments in a cemented, backfilled, stope-ramp intersection at Hecla's Lucky Friday Mine.
-
6/1/2001 - Conference papersNIOSH has developed an entire toolbox of computer programs that have been effectively transferred to the mining community.
