6/1/2010 - Conference papersThis paper presents a mathematical model based on the conservation of mass principle describing the flow of air (nitrogen and oxygen), methane, and carbon dioxide into and out of a sealed atmosphere and time-dependent changes in gas concentration.
-
6/1/2010 - Conference papersThis paper provides an overview of what effects the different exhaust aftertreatment technologies and control strategies available to the mining industry have on the NO2 emissions. Specific focus is given to their effect on the ventilation st...

6/1/2009 - Conference papersThis paper aims to examine the effects of porosity and permeability changes of the coal seam on methane emissions in an underground continuous miner section.
-
6/1/2005 - Conference papersThis paper describes the application of a finite difference program to develop a geomechanical model that predicts permeability changes within the rock mass.

5/1/2005 - Conference papersNIOSH has initiated a reservoir modeling effort to better understand the interaction of the various geotechnical factors influencing gas flow within and to the underground longwall mining environment. A focus of this modeling effort has been (1) the pre...

2/1/1997 - Conference papersIncreasing longwall panel dimensions, particularly face width in gassy coalbeds, may result in unexpected increases in methane emissions. To investigate this problem, continuous longwall face emission monitoring studies were conducted at two adjacent mi...
