We present the articles of the first issue of scientific journal "Mining Science and Technology” (Russia) for 2025:

Scientists conducted laboratory tests according to the International Society for Rock Mechanics (ISRM) methodology to investigate fracture toughness at interfaces between gypsum stone and sand-cement mortar. The fracture toughness coefficient K_IC was determined using cylindrical specimens 40 mm in diameter and 150 mm long with a V-shaped notch, tested in three-point bending. Results showed that the average KIC value for the rock-concrete interface was only 0.323 MPa×√m – 4 times lower than for pure gypsum (1.327 MPa×√m) and 2.5 times lower than for concrete specimens (0.858 MPa×√m). Interestingly, the formation of a calibrated fracture during testing caused a 30% increase in the internal mechanical loss factor Q⁻¹, revealing new possibilities for fracture toughness evaluation using resonance methods. These findings have important practical implications for the design, operation and monitoring of industrial mining facilities containing rock-concrete interfaces.
