Abstract:
Taking the mining area in Tongguan and Daliuta of Shaanxi and Fuxin of Liaoning as an example, the difference of mine geo-environmental problem response to mineral resource exploration and its main factors were discussed by the means of the comparative analysis. The main geo-environmental problems caused by mineral resource exploration in the above three mining areas included as follow: before the 1990s, the mineral resource exploration in Tongguan gold mining area of Shaanxi was very confused, a large amount of waste mining rock lead to severe debris flow and risk, the “three wastes”(i.e. waste gas, waste water and waste residues)discharged disorderly and caused serious heavy metal and cyanide pollutions for soil, river and its sediment, and seriously influenced the human health; Daliuta coal mining area of Shaanxi located at fragile eco-environment zone, twenty-year underground coal mining with heavy machinery caused serious surface collapse and aquifer destroy, but land desertification in the mining area reduced in trend, heavy metal pollutions of soil and water environments were light; for Fuxin coal mining area with one-hundred-year history, surface mining caused frequent landslides, serious land destroy and destruction, land collapse caused by underground exploration had a significant influence on the safety of human life and property, but heavy metal pollutions of soil and water environments were relatively light comparing with metal mining area. Compared with the mine geo-environmental problem of the above three mining areas, the main factors of the difference were mineral resource types, mine geo-environmental condition, exploration methods and environment protection conception.
