为了最大限度回收矿柱资源,缓解矿井接续紧张,延长矿井服务年限,对房柱式采矿法矿柱的力学特性进行分析,着重从矿柱的应力分布、矿柱的受力和变形的一般规律、矿柱上的载荷计算、影响矿柱强度的因素、矿柱的破坏的形式等方面进行分析,为矿柱合理回收提供理论依据。
In order to maximize the recovery of ore column resources, alleviate the continuous tension of the mine, extend the service life of the mine, analyze the mechanical characteristics of the column-and-pillar mining method, emphasize the general rules of stress distribution, pillar stress and deformation , The calculation of the load on the pillars, the factors that affect the strength of pillars, the forms of pillars destruction and so on, providing a theoretical basis for the reasonable recovery of pillars.
