FIELD: mining.SUBSTANCE: method consists in determination of maximum value of convergence of country rocks with account of the design service life of the secured mine, determination of the value of the necessary minimum gap between the beam of the support and rocks of the mine roof, installation of a metal framed support, which is attached to soil by anchors, installation of a pliant element between the beam of the framed support and roof rocks, and the element is made in the form of a round metal pipe. At the same time the pliant element is arranged in parallel to the plane of the support beam, and parameters of the pliant element are determined in accordance with the formula. The pliant element is fixed between two support boards. At the same time the boards are installed in parallel to the pipe axis. The pliant element may consist of two pipes, which are installed mutually perpendicularly and fixed, and the space between the pliant element and the mine roof is filled with material at hand.EFFECT: increasing efficiency of support due to application of pliant elements with high range of deformation and limited controlled force of action at a metal support.4 cl, 4 dwg |
