The paper introduces several mining area examples of Chinese and abroad,pointing out the contamination of ecological environment in the mining activity.

Based on the data of micro-seismic system of Dongguashan and combining the exploiting and geological factors,this paper makes a study of the relationship between exploiting activity and mining-induced seismicity by using statistic and linearization methods.

Through the analysis of the deformation measurement data,ground deformation monitoring data and electronic information-on-demand resonance dating,historical earthquake data and discussion of fault time characteristics,the major reason is a large number of mining activities,not a long-term regional tectonic act.

Studies of the Breeder Individual Precision Feeding System Feeding Behavior Monitor Sub-System;

The distributions of mercury and methylmercury are studied in air, water, soil and some crops in that region affected by gold mining activities, from the point of view of environmental geochemistry.
