矿区生态环境要素的采动损害定量评价方法研究

为了系统研究矿区生态环境的采动损害,必须分析各生态环境要素的采动损害情况,揭示其采动响应机理,并对其采动损害状况进行定量评价。根据采动破坏特点,本文首先分析了矿区生态环境的采动要素构成,并将其划分为建(构)筑物、交通线路、耕地、水环境和地形地貌五大类别。然后描述了各类别的采动响应特征并对其采动损害的影响因素进行了简要分析,在此基础上择取了各要素采动损害定量分析的评价指标。然后提出了各自的采动损害定量评价方法,针对五阳煤矿生态环境的典型采动要素进行了实例分析,分析结果表明评价方法可行,能够满足矿区生态环境采动损害综合分析研究的基础数据需求。

Study on Mining-induced Damage Evaluation of Eco-environment Factors in Mining Areas

In order to study the damage of mining-induced eco-environment,the damage status of eco-environment fac tors must be analyzed.The responding mechanism must be disclosed and the damage must be quantatively evaluated.Accord ing to the characteristics of mining-induced damage,formation of mining-induced ecological environment factor is firstly ana lyzed in the paper.The mining-induced ecological environment factor is divided into such five kinds as buildings,communica tion lines,planation,water environment and topography.The character of every kind of factor responding to mining subsidence is then described.The damage cause is also briefly analyzed.The indexes of damage evaluation are chosen on this basis.The specific evaluating method aiming at each type of eco-environment factor is then presented.The typical mining-induced factors of Wuyang coal mine are chosen for the case study.The result shows that the evaluating method is feasible and can meet the data need for the comprehensive study on mining-induced damage of mining areas' eco-environment.
