7. owing to the primordial matter of coal-forming is different with the palegeology condition of coal-forming, difference due to the initial material of coal-forming and the difference of biochemical action and geochemical factor and the micro-composition of coal petrography, composition and the character of the various coal in different regions have very big-difference, coal is uneven mixture, it is made up of organic substance and inorganic substances two parts, composition and the character of coal and other mineral have very big-difference, mineral are the aggregations that in nature, metal or nonmetallic compound are formed, and metallic ore refers to through smelting the mineral products that can therefrom extract metallic element。Such as ferrous metal mineral products: ferrum, manganese, chromium, vanadium, titanium etc. are the mineral products being used as steel and iron industry raw material。Nonferrous metal ore includes: copper, stannum, zinc, nickel, cobalt, tungsten, molybdenum, hydrargyrum etc.。Noble metal includes: platinum, rhodium, gold, silver etc.。Light metal mineral products include: aluminum, magnesium etc.。Rare metal mineral products include: lithium, beryllium, rare earth etc.。The common feature of most mineral metal products is mainly manifested in the aspects such as quality is harder, glossy。Mineral metal products can be divided into 5 kinds by its Matter Composition, character and purposes: ferrous metal mineral products, nonferrous metal ore, noble metal mineral products, title have dispersed elements mineral products, semimetal mineral products, nonmetallic ore is with metallic ore comparatively speaking, there are 91 kinds, are mainly diamond, graphite, crystal, corundum, asbestos, Muscovitum, Gypsum Fibrosum, fluorite, gem, jade, Achates, limestone, dolomite

The character of coal is divided into physical property, chemical composition, processing performance and combustibility etc., when the depositing dust character of Study on Coal, answering the chemical composition of Study on Coal and the atomic structure feature of institute's component, the physical property of coal includes coal petrography composition, color, gloss, density, hardness, electric conductivity, heat conductivity, thermostability, magnetic, granularmetric composition, argillization degree

The chemical composition of coal includes elementary composition and Industrial Analysis, coal is the humatite changed by plant remains, it is elementary composition sufficiently complex, coal is mainly by carbon, oxygen, hydrogen, nitrogen, sulfur, 6 kinds of phosphorus is elementary composition, possibly together with a small amount of fluorine, chlorine, arsenic, boron, plumbous, the elements such as hydrargyrum, and the germanium of trace, gallium, vanadium, the rare elements such as uranium, the Industrial Analysis of coal is in order that understand Coal Quality, judge kind and the processing and utilization approach of coal, including the moisture measuring coal, ash, volatile matter and fixed carbon, , moisture according to coal and ash can substantially understand the percentage composition of wherein organic substance or combustible, moisture and ash such as coal are high, then the content of organic matter is just few, thus caloric value is low, economic worth is little, character organic coal can be substantially recognized from the volatile matter of coal, the height of degree of coalification, the height of close-burning power and caloric value, its degree of coalification can be substantially judged from the fixed carbon content of coal, evaluate its economic worth,

The processing performance of coal includes the cohesiveness of coal, caloric value, chemism, heat stability, grindability, paste-forming properties,

The Industrial Analysis of coal is to understand Coal Quality, judge kind and the processing and utilization approach of coal, including the moisture measuring coal, ash, volatile matter, with 4, fixed carbon, moisture and ash according to coal can substantially understand the percentage composition of organic substance or combustible in coal, moisture and ash such as coal are high, then the content of organic matter is just few, thus caloric value is low, (1) moisture, the moisture of coal has inherent moisture and free moisture two kinds, free moisture refers in exploitation, transport, washing process is attached to the water in coal particle surface and crack, inherent moisture refers to absorption or condenses upon the water in coal particle internal capillary hole, moisture is more high, the economic worth of coal is more low, coal is being stored by the moisture of coal, transport, processing and utilizing all have impact (2) pit ash refer to coal burn completely after the productivity of residue, pit ash is divided into fixed ash and external ash two kinds, fixed ash refers to the dirt that coal is mixed in coalification course, external ash refers to that coal is in exploitation, transport, the dirt being mixed in storage process, i.e. spoil, it can be removed by washing method, pit ash is more high, quality is more poor, caloric value is more low, high processing and the utilization to coal of pit ash has adverse effect (3) volatile matter, the volatile matter of coal refer to coal with the container of air exclusion under certain high temperature, be heated to certain time after, the liquid (steam condition) decomposing out from coal and gas deduct the product after its moisture, the volatile matter of coal is more high, the degree of coalification of coal is more low, burning is more easily lighted (4) fixed carbon, the fixed carbon of coal refer to coal completely cut off air when Organic substance pyrolytic after remaining residual substance deduct its ash after product, main component is carbon, the degree of coalification of coal is may determine that according to fixed carbon content, fixed carbon content is more high, volatile matter is more low, degree of coalification is more high, fixed carbon content is high, the caloric value of coal is also more high, the processing performance of coal includes the cohesiveness of coal, caloric value, chemism, heat stability, grindability, paste-forming properties, the classification of coal, , the classification of coal is adopted different standards by countries in the world, China standard GB/T 5751-2009 " Chinese Coal Classification " is the standard using degree of coalification and processing performance as classification, coal is divided into anthracite, bituminous coal and brown coal three major types, anthracite makes the index of degree of coalification to distinguish anthracitic group with dry ash free basis volatile matter and dry ash free basis hydrogen content, namely smokeless No. one, smokeless No. two and smokeless No. three。

Bituminous coal adopts two parameters to determine classification, a parameter being to characterize bituminous coal degree of coalification, and another is to characterize the close-burning parameter of bituminous coal, the parameter of bituminous coal degree of coalification adopts dry ash free basis volatilization to be allocated as index, and the close-burning parameters selection caking index of bituminous coal and maximum thick ness of plastic layer or Ah's swelling degree difficult to understand distinguish classification as index, i.e. meager coal, meager lean coal, lean coal, coking coal, rich coal, gas rich coal, bottle coal, in glutinous coal, non caking coal, jet coal

The composition and the character that utilize the various coal in different regions have very big-difference, the magnetic of coal particle is different or contrary, the positive magnetic in a certain ribbing, area, another negative magnetic in ribbing, area, or the negative magnetic in ribbing, a certain area, another positive magnetic in ribbing, area, the electrically difference or contrary of coal particle, ribbing, a certain area positive electricity, another ribbing, area negative electricity, or ribbing, a certain area negative electricity, another ribbing, area positive
