Analysis Of Geophysical Scheme In Mine Geological Environment Evaluation

The mine geological environment has a direct impact on the ecological environment,regional economy and others.In the engineering construction and mining industry,the mining leads to the increase of groundwater exploitation,and the mining collapse is becoming more and more serious.Collapse disaster,"three kinds of wastes" problem,environmental dispute and other problems restrain the economic benefits of mining.Based on this,the application of geophysical methods in mine geological environment assessment is analyzed,which plays a positive role in further understanding and analyzing the mine geological environment change,spatial scale,development,rock characteristics and other information.The research contents of this paper are arranged as follows:The formation mechanism,collapse and development characteristics of mine geological environment are analyzed and studied.In combination with the application characteristics of geophysical methods,the paper analyzes the electrical anomaly,wave impedance anomaly,dielectric constant anomaly and other aspects of rock physical properties,analyzes the advantages and disadvantages of resistivity imaging method,borehole electromagnetic CT method and seismic method.And then we select the suitable combination methods combining the Seismic imaging method and resistivity imaging method according to the characteristics of mine geological environment.After the geophysical method is determined,the geological environment assessment of Yifeng Mining Area is taken as the research object.Starting from the geological environment assessment task of Yifeng Mining Area,the task target of geological environment exploration is formulated,the working arrangement principle of geophysical exploration method is briefly described,and the geological environment assessment scheme is formulated.Through the application of geophysical method,it is found that there are still problems such as collapse,"three kinds of wastes",water pollution and environmental disputes in Yifeng Mining Area,which indicates that the application of image method combined with resistivity imaging method can accurately evaluate the geological environment of the mine.This paper analyzes the causes of the geological environment problems in Yifeng Mining Area,and makes strategies from the perspectives of "three kingds of wastes" treatment,sewage control,natural disaster prevention and so on.Combined with the geophysical method,the real-time monitoring of the geological environment in the mining area is carried out in order to realize the comprehensive improvement of the geological environment governance effect and exploration accuracy in the mining area.
