<p>The system is used for supporting mining tunnels and galleries. Caps are mechanically held together by mountings on parallel girders of a mobile support platform and by bolting systems with spacers in a series of arched support frames made from plugged profile segments. The monolithic caps (5) are bolted between their mountings on the girders (15,16), and the warping is led out across the ends of the caps and laid on the abutting segments (10,9). The overlaps of these segments, directly adjacent to the mountings, are comprised with the suspensions for the caps, as a unit (23,24), removable following application of the clamp connections.</p> |
