THE CHANGE PREDICTION OF THE EARTH’S SURFACE SHAPE AND ENVIRONMENTAL IMPACT ASSESSMENT IN CONSTRUCTION PROJECTS FOR MINERAL RESOURCES EXPLOITATION

矿产开发建设项目中的地表形态变化预测及环境影响评价是减少生态环境影响和破坏，落实国家可持续发展战略的重要环节．本文以马钢龙桥铁矿为例，采用有限单元法预测地表形态的变化，并对地面变形将产生的环境影响进行全面的分析，有针对性的提出切实可行的环保措施，为合理地开发矿产资源，有效地保护生态环境提供科学依据．

The change prediction of the earth's surface shape and environmental impact assessment in constuction peojects for mineral resources exploitation is an important link which can reduce ecological environmental impact and deterioration and implement the strategy for sustainable development of our country. In this paper, taking the iron deposit in Longqiao area as a case, the change of the earth's surface shape were predicted to apply the method of limited unit and its environmental impact were analysed and practicable measure for environmental protection were proposed. That provides scientific basis for reasonable exploitation of mineral resources and effective protection of ecological environment.
