Research Summary

This project developed guidelines to assess ventilation effectiveness in underground coal mines using improved sampling protocols and defining optimal instrument locations for continuous-reading airflow and methane monitors.

This project had five research aims, as follows:

identify potential applications and limitations of integrated air velocity and methane monitoring systems;
develop guidelines to interpret air velocity and methane monitor outputs;
determine the size and concentration of methane clouds at continuous miner faces;
improve knowledge and understanding of airflows in extended cuts; and
define the effects of airflow directions and magnitudes on controlling methane levels in these extended cuts.
