Abstract From coal seam geochemical mechanism of element migration enrichment, the main factors affecting coal element distribution was analyzed, and enrichment of gold source element and its mechanism were discussed in this paper; by adding fixative research coal ash fixed mechanism of the process elements, and the following conclusion was got: the coal rank and the effects of organic matter composition, nano pores between coal and mineral surface properties influences coal element enrichment; ore stratum containing gold, Emei basalt gold and ore-forming fluid provide source components in coal. Coal ash gold element fixed experiments showed that the fixed dose of CaCO3, MgO style can concentration effects of gold element, better than fixative fixed dose of MgO style enrichment of CaCO3, plus fixed agent after burning a concentration effect element content in the sample (C > 1) 69.23%, and in the 13th and 48 Au content in the coal sample average fixed ratio of 1.72.
