Both two forms of mine gas in air have rising movement or trend: a part of mine gas or higher concentration of mine gas in air rises by buoyancy because of density difference; pressure diffusion of molecules of mine gas in air is made by pressure gradient, molecules of mine gas have rising movement or trend because down pressure gradient is usually produced by gravity.
