Experimental Study About The Hazard Of Trace Elements Of Coal

A large number of coal is produced every year in China.So the safety is very important in the production process.Except for the well-known coal dust can explode,but also reduce work surface visibility,Accelerate mechanical damage.Coal dust is also very harmful to the health of coal miners in the workplace.At present,the main consideration in the study of the influencing factors of dust occupational diseases is the influence of coal dust concentration and dispersion on the human body.However,other physical and chemical properties of coal dust have a certain correlation with the harm of coal miners.This paper starts from the characteristics of coal carbon resources,geological features and coalfields,and analyzes the geographical distribution of China’s overall coal resources.Statistical analysis of the occurrence of constant and trace elements in coal dust from different regions and different coal types.At present,there are eighty-eight kinds of elements counted in the earth’s crust.Eighty-six elements have been detected from coal samples and gas samples desorbed from coal using analytical methods.The overall level of trace elements in coal samples from the North China Coal Division is relatively high,and the overall level of trace elements in the South China Coal Division and the Northwest Coal Division Coal is the lowest.Select some coal samples with high trace element content and representative geographical features: Kailuan Group Donghuan Coal Mine,Fenxi Group Hexi Coal Mine,Shenhuo Group Xinzhuang Coal Mine,Yangquan Group Yangquan No.1 Mine,Yangquan Group Changgou Mine,Jindi Company Chiyu Coal Mine,Shendong Group Daliuta Coal Mine Seven different coal mines collect relevant coal samples and focus on them.Analysis coal samples of different geological backgrounds by Industrial analysis,elemental analysis,dust particle size analysis and ICP-MS technology for all-element analysis of trace element content,Analysis of possible hazards of human body by combining different elements,It is proposed that the area where the coal sample is located and the coal mine workers’ dust hazard need to pay attention to the aspects and suggestions:...
