The Influence of Fracture Strain Energy on the Burst Tendency of Coal Seams and Field Application

Abstract: Coal is typically considered a special engineering rock mass because of its low strength, high internal fracture development, good permeability, and random distribution of microparticles and fractures. The results of cyclic loading and unloading tests indicate that the strain energy during the coal deformation process can be divided into three parts: plastic strain energy; fracture strain energy; and base-material strain energy. The energy composition ratio differs depending on coal strength. Lower proportions… Show more

“…Li et al [17] calculated a preliminary estimate of the spatter velocity of broken rock particles based on the principle of energy conservation and provided a set of steps and methods for preliminary analysis of the overall failure mode together with the state and strength of rock mass structure from the perspective of an energy budget. Guo et al [18] studied the mechanical properties and deformation characteristics of rock under uniaxial cyclic loading and characterized the stress-strain curve under each cyclic loading. The stress-strain curve formed a hysteresis loop which translated in the direction of increasing strain.…”
