  Crack instability in deep coal seam induced by the coupling …

  2023101 · Abstract Coal and gas outburst is a violent mechanical instability of gas-containing coal, and its mechanism is crucial for prevention of gas dynamic disasters. The macroscopic instability of gas-containing coal is the result of the expansion and connection of micro cracks driven by unloading induced tensile stress and gas pressure.

  2022111 · Tectonic coal exhibits nonlinear energy storage characteristics, which verifies why the tectonic coal is prone to coal and gas outburst from the principle of energy dissipation. In addition, the damage mechanism of tectonic coal is described from the point of energy distribution by introducing the concepts of crushing energy and friction energy.

  Resistivity and damage of coal under cyclic loading and unloading

  2023920 · The stability of the coal in underground coal mining can be reduced greatly by mining activities and seepage water. Studying the failure and damage evolution of water-saturated coal under cyclic loading is therefore of great importance. Conducting single-axis equal-amplitude cyclic loading and unloading tests of water-saturated coal, this paper …
