摘要
为对安阳3个铁矿采空区的稳定性进行评价,综合选取了8个评价指标,采用层次分析法(AHP)确定指标权重,根据模糊数学中梯形分布的隶属函数对应求出各指标的隶属度,最后通过实例分析,说明了该方法在评价采空区稳定性评价中的科学性和有效性,可对采空区防范措施的制定提供参考和决策依据。
In order to evaluate the stability of mine-out areas in three Anyang iron mine, eight evaluation indexes were comprehensively chosen. Analytical hierarchy process （AHP） is used to determine the weight of indexes. The membership grade of each index was obtained respectively based on membership function of trapezoidal distribution in fuzzy mathematics. Practical analysis shows that this method is effective and of scientific value in evaluating stability of minedout areas, which can provide some reference and decision basis for the preparation of precautionary measure for mindedout areas.
