List of Gaseous Impurities found in Mines
These impurities and requirements in mines environment is discussed below: 1. Oxygen (O2): Oxygen is a colorless, odorless, and tasteless gas with a specific gravity of 1.1047 (heavier than air = 1), a typical miner at rest consumes about 0.005 litres of oxygen every second due to respiration. Similarly, a miner exposed to moderate and extreme workloads consumes 0.03 litres [...]
