Mining Contract: Numerical Modeling of Gas Emissions and Cave Ventilation in Block Caving Mines
Block caving mining presents ventilation challenges which pose serious occupational health hazards. Research under this capacity-building contract focuses on development of practical mine ventilation engineering tools for safe and effective massive underground mining operations. The goal of this research is to develop a predictive tool for mine operators to assess cave resistances and pollutant gas emission rates with respect to cave propagation.
Contract Status & Impact
This contract is ongoing.
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.
