| Abstract: | The article has summarized content and distributive properties of arsenic in coal of main coalbeds and each coal type of main coal-bearing age in Southwestern China area(Yunnan,Guizhou,Sichuan and Chongqing),and correlation with the informa-tions of home and abroad.From analyses discovered that in the Southwestern China area,the richest content of arsenic located in Yunnan province;in each age of coal-bearing strata,the richest content of arsenic located in stone-like coal of cambrian system;in the each coal type,the richest content of arsenic located in Yunnan Province;in each age of coal-bearing strata,the richest content of arsenic located in stone-like coal of Cambrian system;in the each coal type,the richest content of arsenic located in stone-like coal and lignite. |
