11/1/2007 - Conference papersThis paper presents a summary of remote mine firefighting technologies used in U.S. underground coal mines and the results of completed NIOSH research in that area.
-
9/1/2007 - Conference papersThis paper summarizes existing dust control technologies routinely being used in underground coal mine operations, and provides a review of new controls that are being pursued.
-
6/1/2006 - Conference papersTests were conducted in a full-scale ventilation gallery with a model mining machine that simulated airflow created by a dust scrubber. The results showed that operation of machine-mounted scrubbers improved face ventilation when blowing ventilation is ...

6/1/2006 - Conference papersNIOSH is conducting full-scale underground experiments at its Lake Lynn Experimental Mine to identify and remedy existing shortcomings of remote sealing technology in order to develop new and improved technologies for the mining industry.
-
6/1/2006 - Conference papersNIOSH research suggest that by incorporating ventilation planning into the mine planning process, using propeller fans, developing new stopping materials and construction methods, and using long pillars to eliminate crosscuts where possible, the ventila...
-
6/1/2006 - Conference papersThe flow characteristics of both vane-axial and propeller fans were investigated and tested at four large-opening mines to assess the effects of fan location on recirculation and entrainment.
-
5/1/2006 - Technology NewsThe EZ-Up curtain stopping is designed primarily for use as a temporary or portable stopping, although test results indicate that it may remain durable for an extended time. It can be constructed from a variety of fabrics, including standard mine bratti...
-
1/1/2006 - Peer reviewed journal articlesNIOSH recently investigated the performance of a lower-pressure, water-powered in-line series spray scrubber for removing localized airborne dust emitted at the source. Results showed noticeable improvements in airborne dust capture efficiency through ...
-
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...
