摘要： A mine roof and rib support may include a support member having a roof support arm provided at an angle to a rib support arm, the roof support arm defining an aperture for receiving a mine roof bolt, and wherein the support member defines a channel having an opened side surface and two legs extending from the opened side surface to contact the mine roof and the mine rib. A method of supporting a rock formation may include positioning a support member having a roof support arm provided at an angle to a rib support arm, wherein the roof support arm defines an aperture for receiving a mine roof bolt and a channel having an opened side surface and two legs extending from the opened side surface to contact the mine roof surface and the mine rib surface extending a mine roof bolt through the roof support arm aperture.

摘要： An arch support assembly for withstanding the effects of rock burst in underground mines, which includes a spaced aligned series of arch supports, each support having a spaced pair of upright side support columns with an upwardly cambered cap beam arch having opposite ends therefore transversely meeting and secured respectively to the upper ends of the side columns at an obtuse angle. The arch supports are rigidly tied together and provided with a roof supported by the cap beams to provide in combination an arch support assembly. A yielding connection is provided between the upright side columns and the cap beam ends whereby the cambered cap beams are permitted to flex downwardly under an impact load on the roof and the cap beam ends are thereby permitted to extend transversely a controlled limited amount relative to the upright side columns under a yieldable interference friction securement
