Measurements and Simulations of Face Ventilation Effectiveness for Large Diesel Powered Equipment
Proceedings of the U.S. Bureau of Mines Technology Transfer Seminar, Louisville, Kentucky, April 1987 (IC-9141)
Authors: E. E. Thimons (USBM) and C. E. Brechtel (AAI)

Providing adequate airflow to effectively dilute and remove diesel pollutants in large mine working headings is a little researched area. A simulated diesel mucking operation was carried out in the Exxon Colony Pilot Mine in Colorado to establish expected levels of diesel pollutants in dead-end working headings. This heading was nominally 50-ft wide by 30-ft high. Two face ventilation systems were tested using sulphur hexafluoride tracer gas to represent the diesel pollutants. The results of these tests showed that conventional face ventilation systems operating at high flow rates could adequately ventilate diesel equipment in the 600- to 700-hp range, even in a 300-ft-long dead heading.

Ventilation Planning at the Aberdeen Mine
Proceedings of the 6th International Mine Ventilation Congress, Pittsburgh, Pennsylvania, 17–22 May 1997

Andalex Resources, Inc. recently engaged in a ventilation planning exercise that resulted in the construction of a new main fan installation to support longwall coal mining at the Aberdeen Mine. This paper documents the planning process, including underground measurements, modeling, permitting, and construction of the new fan installation.

Ventilation Planning for the El Mochito Mine
Proceedings of the 6th U.S. Mine Ventilation Symposium, Salt Lake City, Utah, 21–23 June 1993
Authors: C. E. Brechtel and A. M. Richardson (AAI), and T. R. Kelly and F. Feero (American Pacific Mining Company, Inc.)

Recent work to upgrade the ventilation system for the el Mochito lead/zinc mine in central Honduras is discussed. Network modeling and underground measurements were used to evaluate cost-effective alternatives for achieving satisfactory ventilation in a complex and expanding underground operation. Both interim and long-term solutions were implemented to make mining possible under difficult conditions.
