1/1/2005 - Conference papersThis paper describes test procedures used to evaluate performance of methane monitors that could be used underground for continuous personal monitoring of methane. The information in this report provides data that allow the reader to make side-by side c...
10/1/2004 - Conference papersThe NIOSH mining research program at the Pittsburgh Research Laboratory (PRL) includes the areas of coal mine dust control and monitoring, and explosion prevention.
5/1/2004 - Conference papersThis study describes how response times of machine-mounted methane monitors were measured by placing the methane sensor heads in a specially designed box where they were exposed to an atmosphere containing a constant concentration of methane.
This paper discusses elements of a stray gas investigation and the analyses necessary to identify the source of a stray gas.
A general overview of the blasting and CO monitoring of a highway construction project is presented and discussed. The use and effectiveness of residential type CO monitors and multi-gas monitors are discussed.
A detailed description of blasting-related carbon monoxide migration from a construction site into nearby residential homes.
2/1/2003 - Conference papersReport on NIOSH studies using a 12-foot diameter sphere to identify key factors that may enhance the levels of CO associated with the detonation of several commercial trenching explosives.
Lightning Propagation Through the Earth and its Potential for Methane Ignitions in Abandoned Areas of Underground Coal Mines10/1/2002 - Conference papersThis paper addresses the question, 'Can lightning cause potential differences capable of igniting methane-and-air mixtures at overburden depths at which underground coal mining occurs?'
Evaluating Performance Characteristics of Machine-Mounted Methane Monitors by Measuring Response Time6/1/2002 - Conference papersThis publication examines a procedure for measuring the response time of machine-mounted methane monitors
6/1/2001 - Conference papersThis publication develops criteria for selecting the best machine locations for monitoring methane and gives recommendations for revising methane action levels for alternative sampling locations.
