Abstract

L'invention concerne un appareil de soutien d'exploitation minière souterraine doté de plaques de protection, comportant un appui transversal jointif et des plaques (2) de protection placées sur deux côtés de l'appui transversal jointif. Un premier dispositif (21) d'entraînement télescopique et une poutrelle courte (22) sont placés dans une poutrelle (12) de l'appui transversal jointif; l'extrémité télescopique de le premier dispositif d'entraînement télescopique est reliée à une extrémité de la poutrelle courte; le premier dispositif d'entraînement télescopique entraîne la poutrelle courte en mouvement le long de la poutrelle; l'autre extrémité de la poutrelle courte est reliée à la plaque de protection; le dessus de la plaque de protection n'est pas plus bas que 300 mm au-dessous des poutrelles de l'appui transversal jointif et n'est pas plus haut que les poutres supérieures (11) de l'appui transversal jointif. Les plaques de protection de l'appareil de soutien d'exploitation minière souterraine présentent un grande aire de contact avec des protections latérales et une importante force de protection, peuvent protéger efficacement des protections latérales hautes, peuvent s'opposer efficacement à l'effondrement et à l'écroulement des protections latérales hautes, et peuvent se déployer et se contracter sans affecter un mouvement avançant de l'appareil de soutien.
