FIELD: mining industry.
SUBSTANCE: invention can be used for fixing the surface of workings in unstable, fractured rocks. The mine grid is made of longitudinal links sequentially interconnected in width. Each longitudinal link is made of wire in the form of periodically arranged loops of an open shape with a trapezoidal shape. The sides are located to the base at an angle of inclination from 78° up to 85°, preferably 81°, and the difference between the bases of the trapezoids is greater than four wire diameters. The sides are made profiled with the formation of ridges in the longitudinal and transverse planes.
EFFECT: functionality of the mine grid is expanded, mobility is increased during delivery to the installation site.
