10/1/2011 - Peer reviewed journal articlesThis study evaluated CO and CO2 emissions from spontaneous heating of a U.S. coal sample in an isothermal oven under different airflow ventilation rates from 100 to 500 cm3/min. Experiments were conducted at oven temperatures of 70, 90, and 100 °C.
A comprehensive guide to establish a program to curtail diesel particulate matter emissions, control pollutants after release in an underground mine environment and reduce exposures using administrative controls.
Effects of Diesel Exhaust Aftertreatment Devices on Concentrations and Size Distribution of Aerosols in Underground Mine Air9/1/2009 - Peer reviewed journal articlesThis paper summarizes the results of a study conducted to evaluate the effects that several types of DPFs, DFEs, and a DOC have on the concentration and size distribution of diesel aerosols in an underground mine.
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.
12/1/2008 - Peer reviewed journal articlesThis paper discusses methods of preventing CO migration, lessening migrated CO, and detecting CO in underground enclosed spaces and may help reduce exposure of area residents to CO and help prevent unnecessary regulations and blasting limitations.
Effectiveness of Selected Diesel Particulate Matter Control Technologies for Underground Mining Applications: Isolated Zone Study, 20048/1/2006 - Reports of InvestigationsThis study evaluated the effectiveness of the state-of-the-art technologies for controlling DPM and gaseous emissions from underground diesel-powered mining equipment using the isolated zone approach.
1/1/2006 - Conference papersToxic fumes generated by explosives have been a concern for blasters, explosive manufacturers, and mining companies. In this study, 10 lb. charges of confined blasting agent were detonated in a closed chamber, and then detonation gases were analyzed.
2/1/2005 - Conference papersDescribes a small-scale field study to identify key factors that may contribute to the migration of CO through the ground.
8/1/1999 - Technology NewsAn apparatus is described that advances the state of the art in gas content testing of coal or rock core samples. The design goals were to improve sensitivity/accuracy, durability, and ease of operation.
1/1/1995 - Reports of InvestigationsMany mines rely on toxic gas sensors to help maintain a safe and healthy work environment. This report describes a prototype monitoring system developed by the USBM that uses light to power and communicate with remote toxic gas sensors.
