Mining Project: Engineering Design for Mine Fire Prevention and Atmospheric Monitoring Systems

Project DetailValue
Principal Investigators
  • Liming Yuan, NIOSH, 412-386-4961
Start Date10/1/2011
Purpose

The objective of this project is to develop engineering data to improve understanding of mine fires and their interactions with mine ventilation networks, atmospheric monitoring systems, and fire detection and suppression systems.

Program Areas
Keywordsfires, underground mining, ventilation

Research Summary

The CFD codes and the new MFIRE 3.0 code will be used to model airflow and its interaction with the suppression system and agent to develop more effective engineering designs for installation of fire detection and suppression systems. This project will complete the validation of the new MFIRE 3.0 program through large-scale and in-mine tests. This project will use CFD codes and the new MFIRE 3.0 code to improve our understanding of the interactions of mine fires on the mine ventilation network, as well as the effects of fires and ventilation on the fire detection and suppression systems. This project will quantify the flammability properties of mine materials, develop a data base of key flammability characteristics, and rank the materials from easily flammable to not readily flammable. This project will also quantify the relative toxicity of these products, and the differences in the properties of smoke that different combustion sources produce.
