在矿柱设计中,确定了矿柱所应承受的外载荷之后,矿柱的尺寸就主要取决于矿柱矿石本身的强度。为使矿柱强度达到最大,所占矿量最少,本文就影响矿柱强度的几个主要因素——矿柱形状、高宽(径)比、端部接触条件及弱面倾角,根据几何相似原理,通过室内模拟试验进行了研究。文中较详细地介绍了这方面的试验结果,可供矿柱设计时参考。 In the design of the pillars, after determining the external load that the pillars should bear, the size of the pillars depends mainly on the strength of the pillared ore itself. In order to maximize the strength of ore pillars and account for the least amount of mines, the paper analyzes the main factors that affect the strength of pillars-pillar shape, aspect ratio, end contact conditions and weak face inclination. According to the geometrical similarity The principle is studied through indoor simulation test. In this paper, the experimental results in this area are introduced in detail.
