Abstract
A support for protection of development workings includes blocks in form of parallelepipeds made of material based on hydraulic binding composition, those are laid one over another with formation of protective strip along the working, each of those has a lug and depressions, and the lug is arranged on the upper facet of the block, and the depressions arranged with possibility of placement of the lugs of neighboring blocks are made on the opposite facet of the block, and yielding elements. For more reliable fixation to each other of the support blocks for protection of development workings at laying those along and across the protection strip, the lug is arranged with length by the whole facet of the block and is directed along the central axis of the block. The depressions are arranged as through cross grooves and are directed in direction normal to the long axis of the block. The central depression is placed at the middle of the block facet, and the following ones – at two sides of that, at distance of separation in protective strip of the neighboring blocks. The yielding elements are structurally not connected to the blocks.
