VENTILATION SURVEY IN UNDERGROUND MINES %

A ventilation survey is carried out to investigate the ventilation system of a mine and to find out the adequacy of the ventilation system, the points of leakage and the extent of leakage, and the steps necessary for further improvement The investigation is generally done in the following three ways ventilation survey UNDERGROUND VENTILATIONPURPOSE AND SCOPE OF VENTILATION SURVEYS A ventilation survey is an organized procedure of acquiring data that quantify the distributions of airflow, pressure and air quality throughout the main flowpaths of a ventilation system The required detail and precision of measurement, and the rigour of the ensuing data analysis depend upon the purpose of theChapter 6 Ventilation Surveys Mine Ventilation Services
