Geoenvironmental Assessment Of The Tonglushan Copper Deposit In Hubei Province

The system collects groundwater,paddy soil,and rice samples from Tonglushan Copper Mine,analyzes the relevant elements of heavy metals,and collects regional geochemical data to identify the distribution characteristics of heavy metals in different media around the mine and evaluate the environmental quality.The main achievement is as follows:1.The content of groundwater around the Tonglushan Copper Mine did not exceed the Class III standard for groundwater.Except for the increase of Cu near the mine,many elements did not increase significantly,indicating that long-term mining activities did not cause pollution to groundwater.2.The results of rice paddy soil survey showed that except for abnormal Cu on the eastern side of the paddy field,there was no strong abnormality on other elements except for Cu,Pb,etc.Big.3.There is a large area of Pb and Cd in rice in the study area,but from the distribution point of view,exceeding the standard in the deposit is not the most serious area,which indicates that the excessive metal in the area is a common phenomenon,not due to mining activity.4.The comprehensive index method and GIS layer superposition method were used to evaluate the environmental quality of different media in the study area.The results showed that,except for serious rice in the study area and poor environmental quality,the other media near the deposit had good environmental quality.5.The geological conditions of the ore type(low sulphide type)of the Tonglushan deposit,and the presence of carbonate surrounding rocks are not conducive to the activation and migration of metallic elements.Therefore,in this densely populated climate and hot and humid climate,long-term mining is not It will cause serious environmental damage.
