Title Blowing versus exhausting face ventilation for respirable dust control on continuous mining sections.
Bibliographic information MESA Informational Report 1059, Mining Enforcement and Safety Administration, Technical Support Center, 4800 Forbes Avenue, Pittsburgh, Pennsylvania 15213, USA, 1977. 11p. Illus.
Abstract This report gives the results of several surveys carried out in United States mines. The results, reproduced in 2 tables, show the definite superiority of exhausting face ventilation. However, this system has the following disadvantages: it requires careful installation to minimise leakage; it may cause secondary airflow in the corner of the face, necessitating the use of a diffuser fan for firedamp control; and physical limitations may cause difficulty in using such a diffuser fan.
