5/1/2012 - Reports of InvestigationsA new test method has been developed by the National Institute for Occupational Safety and Health (NIOSH) and Clean Air Filter (CAF) for quantifying the outside air leakage into environmental cab filtration systems.
-
11/1/2008 - Reports of InvestigationsNIOSH experimentally investigated various factor effects on cab air filtration system performance.
-
3/20/2019 - Reports of InvestigationsRead about the latest best practices for dust control in industrial minerals mining and processing.
-
12/17/2013 - Reports of InvestigationsThis Report of Investigations compares dust levels generated in 20-ft cuts when using traditional exhaust face ventilation without a scrubber to dust levels in 20-ft cuts when using extended curtain setbacks with a scrubber operating.
-
11/1/2006 - Reports of InvestigationsThis report discusses the evaluation of three types of product sizing silica sand structures: a masonry design, a steel-sided design, and an open structure design. An open structure design was superior from both a dust and noise standpoint.
-
1/1/1995 - Reports of InvestigationsDust control modifications were implemented on small, truck-mounted rock drills at surface coal mines. The control techniques showed noticeable improvement in measured dust concentrations around the drills.
-
1/1/1993 - Reports of InvestigationsThe design and evaluation of two total mill ventilation systems are described. Both systems proved to be very effective at reducing respirable dust levels in a cost-effective manner, were easy to install, and required minimal maintenance.
-
1/1/1983 - Reports of InvestigationsIn Europe, water infusion is used widely to reduce generation of respirable dust during mining. Its use in the United States is limited to a few plow operations in the Pocahontas No. 3 Coalbed. This Bureau of Mines report describes the technology for in...
-
1/1/1977 - Reports of InvestigationsThis Bureau of Mines report deals with water infusion of coalbeds, which can control methane emission at face areas during developmental mining and which may sometimes suppress dust. Studies show that water infused into the coalbed flows through the fra...
-
1/1/1974 - Reports of InvestigationsThe periphery of longwall panels in the Pocahontas No. 3 Coalbed is characterized by a zone of reduced permeability that inhibits the natural drainage of methane. However, natural drainage holes drilled during development have been found to reduce the g...
