| 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. |
