Coal Mine Nitrogen Generator for On-demand, Onsite N2

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).

Nitrogen enhanced drainage of CO2 rich coal seams for mining

2017-9-1  Nitrogen injection has also been trialled for enhancing methane pre-drainage for coal mine gas management at a northern Bowen Basin coal mine in Australia . Over a period of 4 months a total of 1.6 million m 3 of nitrogen was injected into a 2.6 km long horizontal well while production continued in adjacent horizontal wells that were approximately 150 m to either side of the injection well.

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.

Pump up the nitrogen - MiningMonthly

2005-4-18  Nitrogen at a purity of up to 99.5% can be produced, though in coal mine applications the purity is set at 97%, based on the experience of coal mines and expert advice. Until recently Air Liquide had not actively pursued coal mining as a growth opportunity but continued interest from customers provided the impetus for a series of investigations, said Air Liquide

Exposure assessment for nitrogen oxides and carbon ...

2009-4-8  The main sources of nitrogen oxides and carbon monoxide in hard coal mining are the diesel engines. Blasting fumes contribute only to a lesser degree and with different exposure characteristic. As crude 8 h-shift averages describing the current exposure situation, we found 1.35 ppm NO and 0.21 ppm NO 2 for the drivers of train engines and one-rail suspended trains.
