A method for protection of development working includes arrangement of a protective-insulating zone, contoured with a breaker support, along the working, at the boundary with worked out space of the longwall,. The protective-insulating zone is arranged in two steps. At the first step the zone is formed in height of extraction power of the seam, of elastic packs in rectangular form, filled with dry quickly curing mineral mix, with laying in layers. At that each next layer of packs is laid normally with respect to the previous one. The layers of the packs are laid in several rows, depending on the parameters of the zone in width, and the last layer is used as thrust one between the formed band and the ceiling of the extracted seam. At the second step to each elastic pack of formed zone, beginning from the lower layer, mine water is fed for formation of quickly curing one-component mix. |
