克里沃罗格矿区[1]在阶段自然崩落采矿法中广泛地采用矿块房式拉底。为了探索在矿块房式拉底时[2]获得等强度矿柱的可能性,曾经用光弹性法在离心力场中进行了一系列试验。共试验了四个模型。为了研究矿柱水平断面中主应力的分布,我们用等厚线的方法进行应力分布的划分。为此,在 The Krivoy Rug Mine [1] extensively uses nugget floor pull-out in the stage of natural caving mining. In order to explore the possibility of obtaining isopsoid pillars when pulling the bottom of a nugget, [2] a series of experiments have been carried out using the photoelastic method in a centrifugal field. A total of four models were tested. In order to study the distribution of principal stress in the horizontal section of pillars, we use the method of isometric thickness to divide the stress distribution. To this end,
