    摘要： An arch useful for withstanding effects of rock burst occuring in underground mines/tunnels. The arch comprises a curved U-section arch provided on both ends with slidingly coupled U-section arch pieces, the coupled top and bottom pieces being provided with at least two guides on both sides. The guides are slidingly coupled with the bottom section aches, the ends of the top section arch being placed on upper holder plates, the upper holder plates being fixed with the bottom sections on both sides. The bottom portion arches also having at least one lower pair of holder plates fixed on both sides below the upper holder plates.

    摘要： The invention provides a yieldable connection between a metallic rod-shaped body and a holding means through which it passes and is intended particularly for yieldable rock bolts (roof bolts) anchor bolts and yieldable props, e.g. for mining and tunnelling. For that purpose shear bodies, e.g. spheres or inclined cylindrical pins are provided between the holding means and the slidable rod-shaped body and project some distance into the cross-section of the rod-shaped body. On sliding of the latter, in the holding means, these shear bodies form grooves in the rod, whereby energy is absorbed.

    摘要： An arrangement for erecting a columnar supporting element of a hardenable flowable material, for a roof of an underground excavation, has a hollow casing for filling with a hardenable flowable material and is composed of two telescopable casing portions each composed of two open-end semi-circular sections, an element for holding the upper casing portion in contact with the roof of an underground excavation and arranged adjacent to the casing, and elements for connecting the semi-circular sections of at least the lower prop casing portions with one another so as to be pivotable about a longitudinal pivot axis which is parallel to the longitudinal axis of the prop casing, and locking the same with one another.

    摘要： A support includes a base member having an open end and a hollow interior, a forcing member having an end extending through the open end of the base member into the hollow interior thereof and having threads thereon and a mandrel or sliding nut capable of engaging the threads of the forcing member at an adjustable position and providing an interfering relationship between the base and forcing members as a compressive load is applied thereto. The support is particularly adapted for use in supporting the roof of a mine.

    摘要： A device for limiting stresses exerted by neighbouring ground on a buried structure which comprises at least two neighbouring elements which form at least one part of the wall of the structure. The stress limiting device comprises at least one longitudinal slidable plate adapted to be connected by one of its edge portions to one of the neighbouring structure elements, at least two longitudinal guide elements adapted to be connected to the other structure element and applied respectively by one of their faces against at least the opposed edge portion of the slidable plate. A plurality of fixing means extend through apertures in the slidable plate and in the guide elements for clamping the opposed edge portion of the slidable plate between said guide elements. At least one of the guide elements constitutes a fishplate. At least the apertures in the opposed edge portion of the slidable plate are disposed in a plurality of spaced-apart longitudinal rows so that the zones located between the apertures of the same row of two adjacent rows form zones of deformation and/or fracture capable of yielding under the fixing means by a sliding of the slidable plate between the guide elements under the effect of forces which may be exerted on the device by the structure elements.
