6/1/2008 - Conference papersThe results of field tests to understand how ventilation and gob characteristics affect the spontaneous heating process causing spontaneous combustion fires in longwall or worked-out gob areas are presented.
-
In this report, several practical guidelines are recommended for controlling longwall coalbed methane. All predictions are based on determinations made for the Pittsburgh Coalbed in southwestern Pennsylvania.
-
2/1/2008 - Peer reviewed journal articlesThis study proposes a principal component analysis (PCA) and artificial neural network (ANN)-based approach to predict the ventilation methane emission rates of U.S. longwall mines.
-
1/1/2008 - Peer reviewed journal articlesMoisture-sensitive roof rocks have contributed to time-dependent roof falls. NIOSH research proves the value of a wet/dry cycling test for rock evaluation.
-
11/1/2007 - Peer reviewed journal articlesUsing coalbed methane reservoir modeling and an artificial neural network (ANN) design for prediction and optimization of methane inflows and ventilation air requirements to maintain methane concentrations below statutory limits.
-
10/1/2007 - Peer reviewed journal articlesThe top five priority hazards associated with underground coal mining equipment have been identified and information about potential contributing factors and controls collated.
-
9/1/2007 - Conference papersThis paper reviews how simultaneous application of three basic elements reduces the methane explosion hazard at coal mine working faces: (1) adequate ventilation, (2) regular monitoring of gas concentrations, and (3) elimination of ignition sources.
-
7/1/2007 - Technology NewsThe International Workshop on Rock Mass Classification in Underground Mining provided a forum for leading practitioners of rock mass classification from around the world to come together and share their methods and experiences with the technique.
-
6/1/2007 - Reports of InvestigationsNIOSH studied technology and methods that could reduce accidents involving surface mining equipment. These proximity warning systems included radar, sonar, GPS, radio transceiver tags, and combinations of radar and cameras.
-
5/1/2007 - Conference papersThis paper discusses the sources used in developing the CMRR, describes the CMRR data collection and calculation procedures, and briefly presents a number of practical mining applications in which the CMRR has played a prominent role.
