A Project Feasibility Study On The Iron Ore Development Of Taiping Ridge

Mineral resources provide an important material basis for the survival and development of mankind,and steel is the basic material for developing the national economy.With the rapid development of China's market economy,the demand for iron products is increasing.In order to promote and active development of local economy and the resource advantage into economic advantage,this study of Taiping hill pools county iron ore geological detailed investigation work,main purpose is to find out the geological characteristics,estimated reserves of iron ore resources,for mine delimit the development and utilization of iron ore mining area as well as the Taiping ridge provide detailed geological basis.At the same time,for iron ore mining technology and the project plan,put forward the environmental harm and protection measures in the process of mining,this paper expounds the problems may meet in the process of production safety,and puts forward the relevant measures which will guarantee the safety of production.Finally,the economic benefit evaluation of this project is carried out,and the rationality and feasibility of this project are demonstrated.The specific conclusions of this study are as follows:(1)Through geological exploration,the distribution of strata,structure,magmatic rocks and skarn in the mining area is basically identified.I control the orebody is 177 m long,control of maximum inclined deep 214 m,average thickness of 6.70 m,TFe grade of 48.80% on average.Exploring quantity of iron ore resources reserves(122 b + 333)of766000 tons,which control the economic basis of reserves(122 b)capacity of 492000 tons of ore,concluded that the intrinsic economic resources(333)the amount of 333 tons,122 b grade ore amount accounts for 64% of the total ore,provides the reliable resources for the development and utilization of the mine.(2)According to the engineering analysis and environment quality present situation investigation,analysis of iron ore mining in construction,mining operation period andretired recovery degree and range of influence on the surrounding environment and ecology and combined with national and local industrial policy,the feasibility of the comprehensive evaluation of iron ore mining is feasible,a clear conclusion(3)Mining engineering technology and engineering solutions for the calculation,design and analysis,at the same time,this paper expounds the hidden dangers for safety and environmental pollution factors in the process of mining,puts forward the relevant prevention and response.It provides clear guidance for mining process and demonstrates the feasibility of the development technology of Taiping ridge.(4)Deposit preliminary technical and economic analysis,the project before tax and tax financial internal rate of return of 19.70% and 14.10% respectively,are greater than the industry benchmark yields 10%,pre-tax and after-tax net present value of 11.0879 million yuan and 5.4254 million yuan respectively,mine production year production value 19.47 million yuan,profit of 3.937 million yuan,at the same time can also be turned over all kinds of taxes and fees for 4.263 million yuan a year,the development of the deposit is technically feasible and economically reasonable.The mining economic benefit and development prospect are good.
