Technical And Economic Evaluation Research On The Reconstructipnr Of YUANBAOSHAN Open-pit Mine

The main research work of the coal business enterprise construction item economicefficiency is to practice empirical foundation in the full market analysis and the forecast andmore similar business enterprise, carry on the finance evaluation, social evaluation andenvironment influence evaluation of science on construction item, and strengthen the economicevaluation research of construction item to coal enterprise, is carry out coal industry efficientlybenefit, can keep on of one of the important assurance measures.Thesis first aiming at the development situation of domestic strip mine and contact withYuanbaosan’s strip mine the place status condition in the coal market of place district, analyze athesis to carry on the purpose and importance of technique and economy evaluation that changesto extend item.On the foundation of studying various evaluation method to the engineeringconstruction item economic evaluation at home and abroad, combine our country concretewealth and properties、 tax system and have relation with national regulation, to the constructionitem economic possibility decision analysis the system carried on a research and combined theactual situation of Yuanbaosan strip mine, the first step built mine engineering investment itemtechnique and economy evaluation model.After contrasting various economic evaluationmethods and calculation model, and specific financial evaluation analysis, environmental impactassessment analysis and social impact analysis and evaluation to the Yuanbaosan.Then accordingto the mineral technique and economy evaluation for central content, as to it’s carry on financialanalysis and evaluation of system, the environment influence evaluation and analysis and societyinfluence evaluation and analysis. Finally passes to build up Yuanbaosan strip mine to changeand extend item of technical and economy synthesizes to evaluate index system andcomprehensive evaluation model, it adopts to analytic hierarchy process to confirm fuzzy andcomprehensive evaluation method under weighting coefficient for analysing the rationality ofextending and changing the item, finally calculation result express that the item grade belongs toa slightly better scope.Evaluate model by establishment and combine Yuanbaosan strip minechange and extend item, getting the economic evaluation of result is objective and accurate, canprovide scientific proof for the governor of mine item.
