Study On Trace Elements Of C~P Coal Seam In ADaoHai Mine

My country is rich in coal resources, complete species, is one of the important basic energy in China. Estimate to the middle of the 21st century, energy consumption of coal in our country is still not less than 50%. But with the development of our country’s economy and the progress of science, as well as to protect the environment, we pay more and more attention to associated beneficial elements and harmful elements in coal to explore and research.This article mainly studied and analyzed the DaQingShan coalfield, ADaoHai of trace elements in the Permo-Carboniferous coal mining area. Precision instruments and equipment have:adopted by the polarization microscope, scanning electron microscope (sem), inductively coupled plasma mass spectrometry, gas chromatography, etc.Average in the north China coal and coal in China, compared to average ADaoHai of trace element in the mining area of Permo-Carboniferous coal sample, the Ga, Ag, Pb, U and Ba content on the high side, in the dirt band and roof V, Cr, Co, Cu and zinc, Ga, Ag, Ba, and Pb content of these elements is on the high side. High mass fraction of trace element levels only elements Be and Se. harmful trace elements U, Pb and Zn (roof and parting) are higher than the average content of coal in China and the world average content of coal. By analyzing the ADaoHai directivity in the Permo-Carboniferous coal mining area element geochemical parameters, this is the main terrestrial facies on the study area are obtained.Permo-Carboniferous coal in the studied area by alternating banded bright coal and dull coal, coal metamorphic degree is higher, the maximum vitrinite reflectance is 1.36%. Coal and rock maceral are mainly composed of vitrinite, idler set times, exinite minimum. O characteristics through the coal facies analysis, that the ADaoHai permo-carboniferous coal mining area are mainly composed of continental, mainly for the shallow water of coal-forming environment in forest and swamp into coal plants for woody plants. In the carboniferous Permian coal minerals mainly include clay minerals, sulfide minerals, carbonate minerals and oxides, etc.The parameters of the saturated hydrocarbons in soluble organic matter of coal plants maturity is higher, and has a higher plant organic matter input. Aromatic hydrocarbon parameters can be analyzed into coal plants to terrestrial plants.
