摘　　要：为了探讨空场法及充填法中采场留设点柱的稳定性,首先分析地质、设计及生产因素等3类13种因素对点柱稳定性影响,其次引入层次分析法(AHP)对点柱稳定性影响因素进行综合评判,并通过建立网格层次结构模型、和积法求解判断矩阵、单排序及总排序一致性检验定量分析评判的安全性。结果表明,AHP法建立的模型可靠,组合权向量符合一致性检验要求。设计因素、地质因素及生产因素对点柱稳定性影响总权重依次为0.62、0.24、0.14,且权重总排序较前的因素依次为点柱形式、点柱大小、采场宽度、矿岩理化性质、点柱间距、爆破振动影响。重点研究影响点柱稳定性的关联因素,可以在回采过程中对这些因素加以控制,从而保证回采过程的安全性,为同类型矿体回采提供借鉴作用。In order to study the stability of pillars in stope with open-stoping method and backfilling method, influential factors on pillar stability are firstly analyzed. Factors include la parameters involved in geological, de- signed and productive factors. Then, AHP is introduced for comprehensive evaluation of those factors. Finally, e- valuation safety is verified with hierarchical structure model building, judgment matrix calculation and sequencing consistency checking. The results show that AHP model is reliable, and its consistency check of combined weight vector meets the requirement. Designed factors, geological factors and productive factors sequentially influence the pillar stability by weight vectors of 0.62, 0.24 and 0.14. Additionally, the shape and size of pillar, stope span, physicochemieal property of mine and rock, space of pillar, and blasting vibration evidently take effect on pillar sta- bility. This paper is focus on the related factors affecting the stability of the pillars. The object is to control these factors to achieve the safety of mining.
