Research On Key Technology Of Dagaozhuang Iron Mine Construction

As one of the important raw materials of modern industry,the supply of iron ore has a great influence on the development of many industries.Through the survey,the development of iron and steel industry and the national economy level has significant relationship,through the national economic development plan to make scientific prediction in advance to predict future demand for iron ore production,and provide guidance for mine construction project development process.Because modern large-scale storage of iron ore resources are all underground and storage,therefore,doing well the technical investigation work of underground iron ore development and construction projects has an irreplaceable significance for the future iron ore supply.This paper first discusses the contents of iron ore reserves,planning and technical measures at home and abroad,and points out the deficiencies and the problems to be improved in the field of iron ore mining in China.Then this paper on domestic iron ore reserves and development situation,and discusses the method of linear regression,grey prediction method of storage capacity in the national economy and iron ore,and puts forward the solution to the current domestic iron ore resources storage volume,price instability and other issues.At the same time,the paper also combines the high iron ore project case,the construction mode of the project selection,multi well multi working face construction scheme and its optimization are discussed,and the analysis of the content of project technical and economic index and optimization results,verify the feasibility of the project.Finally,this paper combined with the layout of the project on the shaft.The ventilation scheme was designed through the analysis and Research on the 6 plan,pointed out the use of 4 and 4 of the ventilation system of the air at the same time,the accounting scheme and fan equipment etc..The contradiction caused by the current domestic iron ore shortage is becoming increasingly fierce,to solve the problem we must start from the technical construction of domestic iron ore,making the technology scheme,can effectively improve the domestic iron ore production,ensure the stable supply of domestic iron ore,and then realize the sustainable and healthy development of the domestic economy.
