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 longitudinally yieldable support for underground roof support includes a first support section with a first elongate outer shell partially filled with a solid compressible filler material and a second support section at least partially filled with a second solid compressible filler material. The second support section is at least partially disposed within the first elongate outer shell and is telescopically extendable relative thereto. A bladder is interposed between the first and second support sections that is fillable in situ to cause extension of the second support section relative to the first support section when filled under pressure with a filler material.

摘要： A plurality of hollow prop casings are provided which are each composed of at least two telescopable sections. These sections are erected by putting them upright and are then telescoped apart until they bear upon the roof to be supported. They are then temporarily arrested in this position and filled with a hardenable substance in flowable condition which, when it hardens, forms a solid column that is able to support the roof. Reinforcing bars or similar elements may be provided in the interior of the prop casings to become embedded in the hardenable substance. Measures may be taken for facilitating disassembly of the prop casings with the solid columns therein, under circumstances in which the casings are subjected to downward pressure by the roof.
摘要翻译： 提供多个中空支撑壳体，每个中空支撑壳体由至少两个可伸缩部分组成。 这些部分通过将它们竖起来竖立，然后将其伸缩，直到它们承受屋顶被支撑为止。 然后将它们暂时停留在这个位置，并充满可流动状态的可硬化物质，当其变硬时，形成能够支撑屋顶的固体柱。 可以在支撑壳体的内部设置加强杆或类似元件以嵌入可硬化物质中。 在壳体受到屋顶的向下压力的情况下，可以采取措施以便于拆卸带有固体柱的支柱壳体。

摘要： An extending prop for underground and tunnel construction, comprising, an outer tube having a closed bottom end, an inner tube telescopically slidable in the outer tube and having a closed top end, and a mechanical locking device adapted to fix the relative positions of the inner and outer tubes. A hydraulically actuated flying piston is arranged in the outer tube and is separated from the inner tube. The piston is adapted to extend the inner tube upon actuation by hydraulic pressure. The piston divides the prop into a bottom chamber enclosed by the outer tube and a top chamber enclosed by the inner tube. A first filling connection is arranged on the outer tube for filling the bottom chamber with a pressure medium for actuating the piston. A second filling connection is arranged on the inner tube for filling the top chamber. The prop is fillable with construction material through the second filling connection over its entire length by displacement of the piston toward the bottom end of the the outer tube.

摘要： A support column for underground mining has a hollow lower column component and a hollow upper column component. The upper column component is slidingly mounted in the lower column component. The bottom of the upper column component is a plate member. The circumferential outer surface of the plate member and the inner surface of the lower column component form an annular gap through which air and water can penetrate, while a non-hardening filler introduced into the interior space of the lower column component through a filling unit cannot penetrate through the gap. The filler accumulating in the interior space of the lower column component causes the upper column component to be moved relative to the lower column component and the support column is clamped between the abutments. The support column can be removed by discharging filler through an outlet opening in the lower column component.

摘要： Support column for underground mining and tunnel construction, composed of a load-bearing outer shell and a core of a substance which is to be introduced in the flowable state and is capable of hardening. The upper column component can be slid out of the lower column component and is secured against being slid into the lower column component by a ring-shaped spring element. Active clamping forces can be introduced by means of clamping devices which can be mounted on the outside.
