NANOSTRUCTURES IN THE THIN LAYER OF COAL SUBSTANCE

In the present work, the surface layer of a coal substance is considered, the structure and characteristics of which are different from the bulk structure. This layer has two levels: d(I) equal to 151,5 nm and d(II) ≈ 10 · d equal to 1515 nm for anthracite. For pure metals d(I) is equal 1 — 6 nm, that is 2 orders of magnitude lesser than the surface layer of the coal substance. The thickness of this layer is of the order of 135 nm for the higher C96 fullerenes. All these features of a coal substance, which has a carbon base and is a polymer with a supramolecular structure, lead to the fact that it is the surface layer that determines the physical processes in it associated with the flow of gases and liquids, as well as with the phenomena of the explosion hazard.
