【 摘 要 】

The technique of initial data preparation for geomechanical substantiation of parameters of mine workings interfaces is offered. The results of the mine experiment on a stressed-deformed state of a rock massif in the intersection of a belt road with a diagonal connection are presented taking into account the spatio-temporal location of the mining face. A comparative evaluation of the results of instrumental measurements and calculated displacements of the roof rocks in the intersection of mine workings was carried out.
