Reservoir Modeling-Based Prediction and Optimization of Ventilation Requirements During Development Mining in Underground Coal Mines2/1/2008 - Conference papersThis NIOSH study presents an approach for prediction of methane inflow rates using coalbed methane reservoir modeling which can be used to limit the methane concentrations occurring as a result of the influences of various coalbed and operational parame...
11/1/2007 - Peer reviewed journal articlesA discussion the spatio-temporal volumetric strains in a consolidated Pittsburgh seam coal sample which were evaluated while both confining pressure and carbon dioxide CO2 pore pressure were evaluated.
Reservoir Simulation-Based Modeling for Characterizing Longwall Methane Emissions and Gob Gas Venthole Production7/1/2007 - Peer reviewed journal articlesThis paper presents the development and results of a comprehensive, "dynamic," three-dimensional reservoir model of a typical multi-panel Pittsburgh coalbed longwall mine. Results presented in this paper include a simulation of gas flow patterns from th...
This chapter summarizes how certain geologic features may be associated with unexpected increases in gas emissions during coal mining. These unexpected emissions have the potential to create explosive conditions in the underground workplace. Also discu...
This chapter gives guidelines for preventing methane gas explosions at continuous miner sections in coal mines, both at continuous miners and at roof bolters. The need to control peak methane emissions is particularly stressed. Emphasis is also placed...
6/1/2006 - Information CircularsThis handbook describes effective methods for the control of methane gas in mines and tunnels. It assumes the reader is familiar with mining.
Development and Application of Reservoir Models for the Evaluation and Optimization of Longwall Methane Control Systems6/1/2006 - Conference papersThis paper describes the development of reservoir models for the longwall mining environment and their application for investigating the influence of various completion design parameters on the methane drainage effectiveness of gob gas ventholes.
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.
Use of Ground Penetrating Radar and Schmidt Hammer Tests to Determine the Structural Integrity of a Mine Seal2/1/2002 - Conference papersOver the years, more than 20,000 mine seals have been erected in underground coal mines in the United States. The National Institute for Occupational Safety and Health is conducting research to develop design guidelines, to investigate noninvasive tech...
9/1/2000 - Conference papersThe importance of controlling respirable dust and methane gas levels in underground coal mining cannot be underestimated. This paper reviews practical applications of water sprays and dust scrubbers to control respirable dust and methane gas on continu...
