3 classification principles

Microscopic coal and rock type is a combination of natural symbiotic microscopic components, the minimum thickness of 50μm or minimal covering an area of \u200b\u200b50μm × 50μm, quantity (volume fraction) in which the microstructure of the packet (or microscopic components) appear equal to or greater than 5% is determined. It may contain less than 20% of the mineral (e.g. clay, silica, carbonate) or less than 5% of the sulfide minerals. If the mineral content exceeds the above number, press microscopy And the proportion of the component minerals are different types of mineralization known as microscopic or microscopic mineral types.
