Sulfur and nitrogen in the high-sulfur coals of the Late ...

2015-09-01  Twenty-five high-organic-sulfur coals of the Late Paleozoic from China were collected from the underground coal mining faces. Fourteen Late Permian coals from southern China, deposited on the carbonate platform, were superhigh organic sulfur (SHOS) coals, of which the vitrinite reflectance (Ro,r) varied from 0.77% to 1.93% (Table 1).

Mine gas mining Britannica

It is a product of the incomplete combustion of carbon and is formed in coal mines chiefly by the oxidation of coal, particularly in those mines where spontaneous combustion occurs. Black damp is an atmosphere in which a flame lamp will not burn, usually because of an excess of carbon dioxide (CO 2) and nitrogen in the air.

Coal Mine Nitrogen Generator for On-demand, Onsite N2

The key initiative in extinguishing a coal mine fire is to reduce oxygen content of the combustive gases below the lower limit of explosion (LEL). Specialty foams are occasionally injected with nitrogen gas to help seal off air ingress to the fire and help cool the surface of the coal embers after the LEL has been achieved. Injection continuously is required for days, even months in

Coal mining - Wikipedia

Coal mining is the process of extracting coal from the ground. Coal is valued for its energy content and since the 1880s, has been widely used to generate electricity. Steel and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production. In the United Kingdom and South Africa, a coal mine and its structures are a colliery, a coal mine is

Sulfur cycle - Wikipedia

Humans are mining coal and extracting petroleum from the Earth's crust at a rate that mobilizes 150 x 10 12 gS/yr, which is more than double the rate of 100 years ago. The result of human impact on these processes is to increase the pool of oxidized sulfur (SO 4 ) in the global cycle, at the expense of the storage of reduced sulfur in the Earth's crust.
