10/1/2007 - Peer reviewed journal articlesTo transfer CFD expertise to analyze and design a face-ventilation system, a comprehensive validation study of current CFD tools against mining-related benchmark experiments is required. This study was dedicated to the methane behavior in an empty (cont...
-
8/1/2007 - Peer reviewed journal articlesThis article focuses on U.S. Bureau of Mines (USBM) and NIOSH research to examine factors that had a significant influence on mine face ventilation design during the past century.

7/1/2007 - Conference papersA cooperative study was conducted to evaluate the effectiveness of (partially) pre-driven longwall recovery rooms supported with pumpable roof supports.
-
7/1/2007 - Conference papersThis paper addresses both the safety and the operational issues associated with mobile roof support (MRS) usage during shield recovery. It also discusses new developments, including the use of the inherently safer battery powered MRS's.
-
2/1/2007 - Conference papersThe fact that methane ignitions continue to occur at the mining face indicates that monitoring with machine-mounted methanometers does not always indicate the presence of high methane concentrations. Methane concentrations at the face change quickly du...
-
6/1/2006 - Conference papersTests were conducted in a full-scale ventilation gallery to determine the influence of mining machine-mounted water sprays on airflows and methane concentrations at the face when blowing ventilation systems are used. Test results using different spray a...

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...
-
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...
-
8/1/2004 - Conference papersThe San Juan Mine and the National Institute for Occupational Safety and Health conducted a study to measure how development mining affected bolt loads.
