1/1/2007 - Peer reviewed journal articlesNoise surveys were conducted in eight coal preparation plants. Results indicate that only workers who routinely spend a significant portion of their shift in the plants (away from the control rooms) are susceptible to overexposure from noise.
-
8/1/2006 - Conference papersA survey of pillar conditions was carried out at 21 operating limestone mines that use the room-and-pillar method. Pillar instability is most likely caused by unfavorable geological structures in pillars with width to height ratios of less than 1.5.
-
12/1/2005 - Peer reviewed journal articlesThis publication describes worker noise exposure surveys in coal mines and coal preparation plants, revealing that worker dosimetry, time-motion studies, and equipment noise profiling are important for effective use of administrative controls.
-
4/1/2004 - Peer reviewed journal articlesA field test of the NIOSH-developed training product "I Can't Get Enough Air" was conducted to determine if it led to improvements in miner's scores on a true/false test of their SCSR's functional capabilities and proper usage.
-
2/1/2002 - Conference papersThe ultimate goal of this research is to develop control technologies to reduce worker exposure to respirable silica dust. Dust surveys were conducted in an underground limestone and gold mine to investigate silica dust sources, generation levels, and ...
-
8/1/2000 - Conference papersIncludes general information on the hearing loss problem in mining, a review of hearing protection used and noise regulations in mining, and other background materials.
-
1/1/1996 - Reports of InvestigationsGround penetrating radar (GPR) has been investigated by NIOSH for its potential to determine roof hazards in underground mines. GPR surveys were conducted at four field sites with accompanying ground truth to evaluate GPR for roof hazard detection.
-
1/1/1988 - Data and statistics, Information CircularsA 1986 probability sample survey, mining industry population survey, to measure such employee characteristics as occupation; principal equipment operated; work location at the mine; present job, present company, and total mining experience.
-
1/1/1977 - Information CircularsThis Bureau of Mines report tabulates methane emissions from U.S. Bituminous coal mines with daily emission rates of at least 100,000 cfd according to states, counties, and coalbeds. Most of the methane emitted is from mines in the Appalachian States. T...
-
1/1/1975 - Reports of InvestigationsGeological surveys were completed in six coal mines to study the overall geology of the coalbed, and to use the resulting data to evaluate the influence of the geological characteristics of the coalbed on safe and efficient coal extraction.
