摘要： The invention is concerned with a self-advancing mine roof support comprising a base, hydraulically extensible prop means mounted on said base and a roof-engaging structure, including a canopy, mounted on said prop means for application thereby to a roof to be supported. On at least one side of the roof support there is a laterally extensible and retractable auxiliary canopy and a device is provided for urging and extending said auxiliary canopy laterally outwardly with respect to the support. The auxiliary canopy on the support bears firmly against a similar auxiliary canopy on an abutment on a neighboring roof support so as to prevent roof material falling between the two supports. Because it is retractable, however, the auxiliary canopy does not interfere with the advance of the supports. Conveniently the auxiliary canopy comprises two box-like members fitted telescopically one within the other. The device for urging and extending the auxiliary canopy laterally may be a pressure-fluid ram, and valve means controlling the pressure-fluid flow of said ram may be incorporated in the pressure-fluid system of a pressure-fluid advancing means for the support so that said ram is automatically retracted or put on open circuit before said advancing means becomes operative to advance the support.

摘要： A roof-engaging assembly for a mine roof support having prop or jack means to engage and support the roof-engaging assembly, comprises a rigid part to engage said prop or jack means, and a roof-engaging part positioned over and resiliently urged away from the rigid part. Preferably the rigid part has a roof-engaging face and a relatively stepped or recessed face below the roof-engaging face, the roof-engaging part being positioned over and resiliently urged away from the stepped or recessed face and towards positions above the roof-engaging face of the rigid part.

摘要： The invention is concerned with mine-roof supports, especially self-advancing mine-roof supports and provides a support comprising a base, a shield inclined downwardly and rearwardly towards the rear of the base and pivotally attached to said base, a roof-engaging canopy pivotally attached to an upper part of the shield, hydraulically; extensible prop means operatively positioned between the base and said shield, and hydraulically-extensible prop means operatively positioned between the base and the canopy. In some preferred embodiments of the invention the shield is a completely non-roof-engaging member and the pivotal connection between the shield and the baseis such that raising and lowering of the shield, by the prop means between said shield and the base, does not involve material angular displacement of said prop means. The pivotal connection between the canopy and the shield conveniently includes a debris excluding joint between said canopy and shield. The space between the prop means supporting the shield and the prop means supporting the canopy is generally designed to provide a safe walkway for miners. The forward end of the canopy may be provided with an extensible and retractable extension bar and/or with a mineral-face-supporting sprag or plate. The support may have a side anti-flushing shield at at least one of its sides and said anti-flushing shield may be extendable and retractable laterally with respect to the support.
