The U.S. Bureau of Mines, in cooperation with the Mine Safety and Health Administration (MSHA) and the mining industry, has identified and demonstrated the effectiveness of several improved face ventilation techniques for longwall mining systems. These include the following: identifying improved techniques for measuring face ventilation parameters on longwall sections, installing curtains at the intake end of the longwall face to maximize usage of the primary airflow, identifying optimum face airflow rates for maximizing dilution effects, and coursing the primary face intake from tailgate to headgate to minimize outby airflow contamination. Application of these techniques throughout the mining industry should reduce the health hazard associated with excessive exposure to respirable coal mine dust.

These research papers also cover a spectrum of innovative technical solutions, including computer-controlled mining equipment, remote monitoring of air quality, and virtual reality training systems.

Diese überarbeitete Auflage behandelt die spezielle Problematik der Minenbelüftung und -klimatisierung als Teil der umfassenden Umwelthygiene der Minenatmosphäre. Diese Thematik wird besonders unter dem Aspekt der technischen Realisierung beleuchtet. Dieses Buch vermittelt einen umfassendenden Einblick in die Umweltbedingungen eines unterirdischen Arbeitsplatzes und die sich hieraus ergebenden Konsequenzen für Gesundheit und Sicherheit. (11/97)
