METHOD FOR PROTECTION OF MINE WORKING AT DEVELOPMENT OF MINERAL SEAMS

摘要

A method for protection of mine at development of mineral seams includes penetration of mine working in worked-out space of face in zone of stabilization of rock pressure according to which in worked-out space of face one forms and supports band of competent formations through installation at its both sides of yielding protection elements, and after band of competent formations goes out to zone of stabilization of rock pressure one performs blasting of rocks of base with placement of rock in worked out space, replacement of yielding protection elements by supports with restricted yield and increased rigidity.
