Introduction to Ventilation
In underground mining ventilation is a necessary part. The purpose of ventilation is to full-fill the supply of oxygen for the working of men and machinery. It also clears the fumes, fogs or damps from the underground mines. We can say the working of mines is directly depends upon this. So let's know more details.... Fan ventilation system by a duct There are two main routes of ventilation 1. Intake :- The intake is the path from where the atmospheric air enters to mines. Intake air is fresh air because it comes directly from the atmosphere. 2. Return :- It is the path from where the contaminated air comes out from the mines. The contamination are of dust, firedamp, CO and also other types of fumes in small percentage. That's why it is necessary to check the presence of different gases on regular basis by which you can predict the emission of different types of gases. These are main routes but there are many sub routes are divided in Mines. These sub routes use...
