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.
-
1/1/2008 - Peer reviewed journal articlesThe work presented in this paper focuses on the relationship between the PDM and respirable dust concentrations currently measured by a coal mine dust personal sampler unit utilizing a 10 mm Dorr Oliver nylon cyclone.
-
12/1/2007 - Peer reviewed journal articlesComputational Fluid Dynamics simulations were conducted to investigate the spontaneous heating of coals in longwall gob areas with different apparent activation energies and reaction surface areas. The results are reported in this paper.
-
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.
-
7/1/2007 - Peer reviewed journal articlesThis paper describes an analytical study to quantify the safety integrity of a Programmable Logic Controller based Emergency Shutdown System and a hardwired Emergency Shutdown System.
-
2/1/2007 - Peer reviewed journal articlesThis paper describes three mechanical methods - the mobile manipulator, the in-mine hoist, and a cable-handling system - developed by NIOSH to reduce injuries related to handling supplies or material, loading and unloading, and moving power cables.
-
2/1/2007 - Peer reviewed journal articlesTo evaluate how elemental carbon (EC), a surrogate of diesel particulate matter (DPM), predicts DPM, measurements of total carbon (TC) and EC were taken away from potential interferences in four underground metal/nonmetal mines during production.
-
2/1/2007 - Peer reviewed journal articlesA study of ground behavior, reinforcement performance and stress redistribution looked at a longwall tailgate under severe horizontal stress. Comparison to field results showed that a FLAC-2D model captured the significant roof and support behavior.
