Resilient mobile mine support system - has cellular structure formed by flexible partitions and elastic fluid inflated chambers

摘要

The resilient moving support system is used for working steep seams in an underground mine and consists of cellular mattress structure. The covering, supported by a chamber of elastic material, is filled with fluid under pressure, so that sides are in contact with pit sides. The support system is formed by a series of additional elastic fluid-filled chambers (10), set close together when inflated so as to provide a closed layer with a resilient covering (2) fitted to its bottom edge. Adjacent chambers (10) are separated by flexible partitions (3), connected to the top and bottom resilient covering (1,2), forming a cellular structure. This permits spreading according to seam thickness, creation of an adequate working space, and more complete mineral extraction.
