Analysis of Abnormal Airflow Quantity in Coal Mine Ventilation

摘要

The abnormal airflow quantity occurring in an airway may be hidden troubles resulting in severe disasters in a coal mine. It's necessary to find out the reason of abnormal airflow and eliminate hidden troubles immediately. In this paper, the criterion of judging the abnormal airflow quantity is put forward firstly. Then the way and process of analyzing the abnormal airflow quantity analysis are introduced step by step. In the end, the analysis software is implemented, which will be helpful to the coal mine safety.
