基于层次分析法的排土场稳定性分析

影响排土场稳定性的因素众多,主要分为内因和外因两大类,控制内因参数是在排土场使用过程中保持排土场稳定性的主要措施。因此,在众多内在影响因素中找出主要因素,并对其加以控制,对于保持排土场稳定性有重要意义。本文以云南某露天金属矿排土场为工程实例,运用层次分析法分析影响排土场稳定性的内因各指标的影响权重,确定主要影响因素,并运用FLAC3D数值模拟对层次分析法的分析结果进行验证,确定了控制排土场堆高是保证排土场稳定性的有效措施。

Analysis of Stability of Dump Based on Analytic Hierarchy Process

There are many factors affecting the stability of mine, mainly divided into two categories： internal and external causes. The parameters of the intrinsic factor which influence the stability of mine, in the process of mine use,is the main measures to keep the balance of mine. So it′s necessary to find the most important factors and try to control them, it is meaningful to keep the stability of mine. The article based on an open metal mine of Yunnan province,analyzes the internal factors affecting the stability of dump the influence of the index weights with using the analytic hierarchy process（ahp）. The purpose of this way is to find out the main factors which influence the stability of mine. By the way,the paper uses FLAC3 D numerical simulation to check out the results of the analytic hierarchy process, to determine that the control of dump height is the effective measures to make sure the stability of mine.
