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 papersIn this NIOSH study, a computational fluid dynamics (CFD) model developed in previous work is used to model the effect of seal leakage on spontaneous heating of coal in longwall gob behind the seal.
-
3/1/2010 - Conference papersNIOSH conducted full-scale fire suppression experiments, and this report discusses the large-scale experimental configuration, installation of the fire suppression system, and conclusions regarding the effect of air velocity and other factors.
-
2/1/2010 - Conference papersThis paper describes lab experiments to examine the effect of spray type, pressure, machine body blocking sprays, and scrubber airflow on dust and gas levels while using a 12.2 m (40 ft) exhaust ventilation curtain setback from the face.
-
11/1/2009 - Conference papersThis paper seeks to encourage scientific discussion among international peers since preventing explosions within sealed areas is of interest to underground coal operators and regulators.
-
10/1/2009 - Conference papersThis report describes a new seal testing program that will provide essential validation data for mine seal analysis and design methods.
-
2/1/2009 - Conference papersThis paper describes the effort to create a reliable in-mine mobile plant for extracting nitrogen gas from the mine atmosphere. The gas produced by this novel technology can be used to create an inert environment in sealed mine areas.
-
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...
-
2/1/2010 - Conference papersThis paper discusses the role of ventilation modeling in evaluating primary escapeway pressurization in a three-entry development system to improve emergency escape in a coal mine using belt air.
-
2/1/2010 - Conference papersThis paper presents an overview of a novel PSA (pressure swing adsorption) plant, the details of the gas injection tests and CFD modeling work.
