    Abstract: A yieldable mine post system having a yieldable mine post construction, made of metal and in telescoping form. The post of the invention comprises a pair of mutually telescoping metal post lengths. The innermost tubular post length has a medial bubble portion of enlarged girth which is oversize relative to the nominal inside diameter of the outermost tubular post length. The result, consequently, is not only to increase the frictional resistance between the post lengths but also to create a bubble zone characterized by elastic/plastic mutually inter-cooperating radial deformation and elastic stress-loading of the telescoping post construction, for further progressively increasing resistance of the composite post structure to compression end loading of such post. The yieldable mine post construction can be made adjustable and also radially preloaded and preset for immediate, desired load resistance. A mine vehicle can also be provided, not only for transporting the yieldable mine posts to a mine site, but also be operative to lift and erect in vertical or other positions such mine posts. The vehicle may have hydraulic or other means for axially rotating and thereby tightening the posts in position.

    Abstract translation: 一个可屈服的矿位系统，具有可收回的矿柱结构，由金属制成并以伸缩形式。 本发明的柱包括一对相互伸缩的金属柱长度。 最内管状柱长度具有相对于最外管柱长度的标称内径尺寸过大的扩大围的中间气泡部分。 因此，结果不仅增加了柱长度之间的摩擦阻力，而且还产生了以伸缩柱结构的弹性/塑性相互协作的径向变形和弹性应力加载为特征的气泡区，以进一步逐渐增加 复合柱结构对该柱的压缩端装载的阻力。 可屈服的矿柱结构可以做成可调节的，也可以径向预加载和预设，用于即时，期望的负载阻力。 还可以提供矿山车辆，不仅用于将可屈服的矿场运送到矿场，而且还可以垂直或其他位置抬升和竖立这样的矿井。 车辆可以具有用于轴向旋转的液压或其它装置，从而将支柱紧固在适当位置。

    Abstract: The invention concerns a mine prop which has a cutting device and a cuttable plunger. The cutting device has a sleeve and a cutter which is fixed to the sleeve and which presents cutting edges transverse to the sleeve axis and axially oriented openings between the cutting edges. A vacant space exists in the sleeve beyond the cutting means. The cuttable plunger projects from the sleeve with at least a portion of the plunger extending within the sleeve to the cutter. When compressive loading applied to the mine prop is of sufficient magnitude to cause the cutting device and plunger to telescope together, the cutting edges of the cutting means cut axially through the cuttable plunger. The resulting segments of the plunger pass through the openings into the vacant space where they are restrained within the sleeve.

    Abstract: A mine support post having a yieldable mine post construction, made of metal and in telescoping form. The post of the invention comprises a pair of mutually telescoping metal post lengths. The innermost tubular post length has a medial bubble portion of enlarged girth which is oversize relative to the nominal inside diameter of the outermost tubular post length. The result, consequently, is not only to increase the frictional resistance between the post lengths but also to create a bubble zone characterized by elastic/plastic mutually inter-cooperating radial deformation and elastic stress-loading of the telescoping post construction, for further progressively increasing resistance of the composite post structure to compression end loading of such post. The yieldable mine post construction can be made adjustable and also radially preloaded and preset for immediate, desired load resistance. In a preferred form, the mine post has as a medial bubble portion a separate part pre-inserted in the outermost tubular post length, with the post lengths being severable, together with a threaded adjustment member provided, for ease of transport.
