Mine Atmosphere Environment

Mine atmosphere consists of physical and chemical characteristics of mine and its ambient air. The physical characteristics mainly include temperature, humidity, wind speed, atmospheric pressure, and precipitation. The chemical characteristics mainly refer to the chemical composition of the air. Mine air pollutants mainly include toxic gases such as carbon monoxide, nitrogen oxides, hydrogen sulfide and sulfur dioxide, smoke, and mine dust. In the process of mining, ore crushing, screening, transfer, waste rock and tailings stockpiling, and in their daily life, mining enterprises discharge various inorganic or organic gases, as well as smoke and dust to the ground of mining area (as shown in the Fig. 1) and underground space. In the process of mining, dust enters the atmosphere in the mining area. A certain concentration of dust after enough time will deteriorate the air quality of the mining area, subsequently harm people’s life and health and destroy the atmospheric environment of...
