9/1/2014Research Concept
A better understanding is needed of the exact behavior of longwall ventilation—specifically, the ventilation of bleeder and bleederless gobs, where flammable or explosive concentrations of methane are known to exist. This research expands on previous work on computational fluid dynamics (CFD) modeling and uses FLUENT code to develop a modeling and predictive tool for mine ventilation.Topic Areas
Explosion Prevention
Ventilation Overview
Contract Status & Impact
This contract is complete. To receive a copy of the final report, send a request to mining@cdc.gov.
The purpose of capacity-building contracts is to help build the capacity of our nation’s workforce to address critical safety and health problems in U.S. mines by producing graduates with advanced degrees in mining and minerals engineering, and to help develop tenure-track faculty performing research in these areas. Applications for these competitive grants are announced as part of NIOSH OMSHR’s Broad Agency Announcements and are submitted by a Principal Investigator at a U.S. institution offering an ABET-accredited undergraduate degree in mining or minerals engineering.
For further information on capacity-building contracts, please submit a request to mining@cdc.gov.
