Research Of Comprehensive Treatment Model Of Mine Eco-geological Environment In Baisha Village, Wu'an City

Based on the mine environment treatment project of Baisha Stone Material factory,the paper studies the mine environment comprehensive treatment model.This paper puts forward a practical classification method of mine environmental problems,which is based on the classification of mine environmental damage forms,including the mountain slope,the residual towering mountain,the irregular mining pit,the loose waste accumulation,and the related type of tailings pond.This paper expounds the classification principle and the detailed contents of each classification,conducts the environmental investigation and problem analysis on the research area by this method,obtains the main damage pattern characteristics and the occupation area of the research area,analyzes the main environmental problems,and carries on the qualitative and quantitative evaluation on the environmental problems in the research area.Based on the analysis of three kinds of common open-pit mine treatment technologies,the characteristics and applicable conditions are discussed.According to the treatment objectives of the research area and the analysis results of environmental problems,the appropriate treatment technologies are selected and optimized,and the design schemes of engineering treatment,ecological restoration and auxiliary engineering are formulated.Taking the spatial planning positioning of the research area as the starting point,the main function and development direction of the area should be clarified,and the development goal should be determined as the construction of characteristic cultural tourism area.Then,the location of the research area was studied to determine the location advantage,economic advantage,cultural advantage and tourism resource advantage.The land productivity of the mining area was reconstructed from the four aspects of ecology,agriculture,culture and tourism,and the future development contents of the research area were planned.Comprehensive the above research,this paper puts forward a kind of open-pit mine comprehensive governance model(GST),expounds the mode constructing principles,methods,and takes the research area as an example to elaborate the construction process.The mode is composed of Engineering Treatment Module(G),Ecological Treatment Module(S),Land Development and Planning Module(T),with the characteristics of development,comprehensiveness and applicability.At present,the project treatment and ecological restoration in the research area are carried out simultaneously.Slope cutting and vegetation greening projects have been carried out on local steep slopes and residual mountains,which has eliminated the hidden danger of serious geological disasters and improved the local ecological environment.The treatment effect is remarkable.The comprehensive treatment mode of open-pit mines has played a good demonstration role in environmental treatment of the same type of open-pit mines in Handan city and even Hebei Province,and provided new ideas and methods,which has certain significance for promoting the environmental treatment of open-pit mines in Hebei Province.
