Coal Mine Nitrogen Generator for On-demand, Onsite

The primary application for nitrogen gas use in the mining industry is extinguishing coal mine fires. However, updated regulations require miners to inert abandoned/worked-out areas of the mines if insufficient seals are installed (note: this is mandated by Final Standard 30 CFR Part 75 issued by the Mine Safety and Health Administration (MSHA) as of April, 2008).

Selection and characterization of coal mine

Coal open pit mining in the South of Santa Catarina state (Brazil) was inappropriately developed, affecting approximately 6.700 ha. Re-vegetation is an alternative for the recovery of these areas. Furthermore, the use of herbaceous legumes inoculated with nitrogen fixing bacteria is motivated due to the difficulty implementing a vegetation cover in these areas, mainly due to low nutrient availability.

1997-8-1  There are contributions of fixed nitrogen in precipitation, 10–30 kg N ha −1 per year, due to industrial pollution and atmospheric processes. But the main source is biological fixation, depending on nitrogen-fixing micro-organisms associated with plant roots, mainly Rhizobium and various actinomycetes. The fixed nitrogen accumulates in the plants and then passes to the soil where it

2008-7-1  The poor availability of nitrogen to plants growing in mine spoil may be due to the lack of mineralizable organic nitrogen and to lower mineralization rates (Reeder and Berg, 1997). As the spoil was low in nitrogen content, plants were inoculated with nitrogen fixing strains of microorganisms to fulfill the nitrogen requirement of the plant.
