Water-Tight Stratum Rupture under Large-Scale Mining. Part II

摘要

The mathematical modeling of variations in the stress-strain state of a water-tight stratum under large-scale mining has been carried out in the frame of the calibrated geomechanical model of the said stratum. The authors assessed the mining impact using the movement trough parameters, found the mechanism for the shear and tensile crack formation inside a water-tight-stratum and worked out the criteria to assess its disturbed continuity.
