摘要： A load bearing support includes a cylindrical drum. A top portion, a bottom portion, a tapered cylindrical sidewall extends between the top and bottom portions. A core member extends between the top and bottom portions, and a load-bearing material is disposed between the sidewall and the core member. An opening extends through the top portion of the drum to receive load-bearing material. Each of the top portion and the bottom portions has a reinforcing chime. The core member includes a lateral transfer zone defined at one or more points along a vertical axis of the core member. The lateral transfer zone distributes an axial load on the drum to the cylindrical sidewall. The cylindrical sidewall provides a radial expansion area for compression of the core member and the load-bearing material.

摘要： A mine prop includes a first pipe having a first end and a second end, a second pipe having a first end and a second end, and a yield member secured to the second pipe. The second pipe is slidably received in the first pipe. The yield member is configured to yield before the first and second pipes when the mine prop is placed under a predetermined load.

摘要： There is a support for underground mining and tunnel construction, comprising an outer tube and an inner tube, which can be pushed into each other in a telescoping manner. A piston acted upon by a hydraulic pressure medium is located in the outer tube. This piston, when acted upon by pressure, acts on the inner tube to cause an extension. The outer tube and the inner tube can be fixed on each other by means of a mechanical locking device.

摘要： A method and an arrangement are disclosed for supporting a roof of an underground excavation. A hollow prop casing of two or more telescopable sections is erected and telescoped apart until it bears on the floor and the roof. The sections are then biased against the floor and the roof and the prop casing is filled with a hardenable substance which upon hardening forms in the casing a solid column capable of supporting the roof.

摘要： This invention relates to a mine support for use in a hard rock deep level mine in which the hanging and foot walls in stopes are subject to closure. The support consists of a timber load-resisting element which is tightly housed in a sleeve of material which has a variable effective length and is adapted to contain transverse spread of the timber while the support is being compressed by the closing hanging and foot walls. It is essential to the invention that in use the grain of the timber element lies in the direction of the compressive 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.
