FIELD: mining. ^ SUBSTANCE: method involves rolling of model of rock mass from equivalent materials, construction of mine working in it, attachment of its roof with anchor support, further specified loading of mass and measurement of deformations and displacements of roof in it. Rigid support is installed in mine working; the distance from the support to the roof of mine working is accepted equal to roof displacement value for the specified time period, considering geometric scale of simulation, the model is loaded until the roof of mine working is lowered down to rigid support; after that, anchor support is built and rigid support is removed. ^ EFFECT: higher attachment efficiency of mine workings by means of steel polymer anchor support by determining the required time of attachment of roof after its uncovering. ^ 2 dwg |
