Abstract: To reveal the evolution characteristics of impacts of mining subsidence on soil chemical properties induced by super-large working face，which would provide a scientific basis for ecological self-healing in mining area.Samples were taken from certain Daliuta working face，including pre-mining，mining，post-mining and surface stability in control area and mining area respectively，and the data were analyzed for soil nutrient contents.The results show that：soil pH value increased with the extension of exploitation schedule and then gradually inclined in the period of surface stability；organic matter，available phosphorus and total nitrogen inclined first and then increased with the extension of exploitation degree；available potassium continuously increased which was different from other indexes.Soil nutrient contents were basically consistent with control area after surface stability，and it shows certain self-heal ability.
