Modeling of the stress-strain state of the rock massif in the vicinity of mining workings in the area of tectonic disruptions

A brief analysis of geological and geomechanical characteristics was performed in the area of the iron ore deposits of Gornaya Shoria, where there are small and large-amplitude faults, including faults with a thickness of 0.4–10 m, their movements along the fault planes, especially during mining operations that provoke geodynamic phenomena. It was determined that the intensity of geodynamic phenomena is influenced by the angles of encounter of workings with tectonic faults and their thickness. Mathematical modeling is used to estimate stress-strain state in the vicinity of workings in the area of tectonic zones. For the calculation, 3D models were built: a 3D model of the mine, located on the side of the hanging side of the disturbance with a thickness of 1–4 m and an angle of 80°; workings located on the side of the prone side of the disturbance with a thickness of 2 m and an angle of 30°. The distribution of high compressive vertical and horizontal stresses, maximum tensile deformations and displacements in the rock mass at various distances from the working face and the location of faults has been established. Rational distances of 2.5 (12) ÷ 17 m were determined, at which preventive measures should be applied.
