Summary

There have been many recent improvements in mine ventilation, a critical component of mine safety. Presenting contributions from a group of renowned researchers from North America, this book contains the proceedings of the 11th US/North American Mine Ventilation Symposium held at Pennsylvania State University in June 2006. Two main topics of special interest discussed rigorously in this reference are coal mine methane capture and utilization and diesel issues for underground and surface mines. In addition to these main topics, other contributions address mine dust, mine fires, ventilation in large-opening mines, and numerous other topics exploring recent advances in mine ventilation technology and practice.
