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.
-
1/1/2007 - Peer reviewed journal articlesSome of the issues affecting pillar strength at low width-to-height ratios in hard, brittle rock are investigated. The results showed that the strength of slender pillars is more variable than that of wider pillars.
-
12/1/2006 - Peer reviewed journal articlesThis paper presents the results of NIOSH research to identify state-of-the-art bulkhead designs, including design criteria, leakage monitoring systems, and emergency warning systems.

The Effects of Water Spray Placement for Controlling Respirable Dust and Face Methane Concentrations4/1/2006 - Peer reviewed journal articlesA series of laboratory evaluations examined the impact of water spray pressure, curtain setback distance, and external and underboom spray use for controlling respirable dust levels and sulfur hexafluoride tracer gas concentrations around a continuous m...

2/1/2006 - Peer reviewed journal articlesThis article compares the performance characteristics of various support systems, including wood cribs, can supports, cluster props and pumpable supports.
-
1/1/2006 - Peer reviewed journal articlesMine seals can be remotely constructed in underground coal mines through vertical boreholes when direct access to a fire is impossible or considered to be too dangerous. Full-scale remote mine seal construction research is being conducted at the Nationa...
-
1/1/2006 - Peer reviewed journal articlesNIOSH conducted four diesel-fuel fire experiments with specific fire heat-release rates to determine the reversal of smoke products-of-combustion from a mine fire in a mine section with the airway connectivity of an electrical Wheatstone bridge.
-
1/1/2006 - Peer reviewed journal articlesA test system was developed at NIOSH's ventilation test gallery to measure airflow using a three-axis ultrasonic anemometer. The gallery was used to simulate face airflow conditions in underground mines having a blowing curtain. Airflow data were used t...
-
1/1/2006 - Peer reviewed journal articlesResults of diesel fuel fire experiments were conducted to determine the critical air velocity for preventing smoke rollback. Experimental results compared well with model predictions based on a computational fluid dynamics fire dynamics simulator.
-
4/1/2005 - Peer reviewed journal articlesDiscusses a study that used a CFD program (fire dynamics simulator) based on large eddy simulations (LES) to model floor-level fires in a ventilated tunnel. The CFD results are compared with two simple theories of critical ventilation.
