摘要： A longitudinally yieldable support for underground roof support includes first and second outer shell portions having a first wall thickness and a third outer shell portion having a second wall thickness that is greater than the first wall thickness. The support is filled with a solid compressible filler material. At least one air ventilation tube extends between opposite sides of the third outer shell portion to allow a flow of air through the support as the first and second outer shell portions and filler material therein yield under load.

摘要： A longitudinally yieldable support for underground roof support includes a first support section with a first elongate outer shell filed with a solid compressible filler material and a second support section filled with a second solid compressible filler material with a second elongate outer shell extending above the first elongate outer shell. The second support section has density that is greater than a density of the first solid compressible filler material. A pair of attachment members are coupled to the second elongate outer shell and are configured for lifting the second elongate outer shell relative to the first elongate outer shell and for securing the second elongate outer shell relative to the first elongate outer shell once lifted.

摘要： A mine prop is comprised of an elongate tube having a slenderness ratio that would generally allow buckling or kneeling of the elongate tube when exposed to a sufficient axial force. A plurality of elongate support members having a length less than the elongate tube are attached to the tube to prevent buckling or kneeling of the elongate tube along the portion of the tube to which the elongate support members are attached. The portions of the tube that are unsupported by the elongate support members define one or more yieldable zones proximate at least one end of the tube. A compressible filler material is disposed within at least portion of the tube to support yielding in the yieldable zone.

摘要： A mine roof support comprises two or more frusto-conical, tubular sections, the sections each flared outwardly from an upper end to a lower end thereof, a skirt portion of a section being received and secured within a neck portion of a section below in a frictional fit to define a continuous, interior volume of the mine roof support. A continuous, solid, compressible, load-bearing material is located within the interior volume. An uppermost section is closed at an upper end thereof, and a lowermost section is closed at a lower end thereof. Methods of installing a mine roof support and a pre-installation assembly for a mine roof support are also disclosed.
