摘　　要：选择有两种采矿模式的江西星子大排岭高岭土矿区,运用成本效益分析原理,从生态效益、经济效益、社会效益三个方面分析评价洞采与露天开采两种模式下的环境影响价值问题。用综合效益系数和综合功能系数来表达两种采矿模式的环境影响程度。通过评分比较发现,研究区洞采模式的综合效益系数大于露天开采,洞采的矿山森林生态系统综合功能得分是露天开采的1.8倍。Takes a kaolin mining area located in Dapailing of Xingzi county of Jiangxi province as an example.Two different mining modes whose environmental impacts are different exist in the mining zone.In the paper,cost benefit analysis is a guide to environmental impact assessment of different mining mode.Benefit analysis of environment variable includes ecological benefit,economic benefit,and social benefit.And the extent of the environmental damage is identified by synthesis index of benefit and comprehensive function index.According to grade of environmental impact,works out that underground laneway digging′s synthesis benefit index is more than opencast working′s,and the mine ecosystem′s comprehensive function index of the former is 1.8 times to the latter.

关 键 词：采矿模式 矿山环境评价 成本效益评价法 环评方法
