What is Experimental Investigation Into Damage and Failure Process of Coal-rock Composite Structures with Different Roof Lithologies Under Mining-induced Stress Loading about?
Coal burst is essentially a destructive manifestation of stratigraphic structure. Although the failure mechanism of the structure has been extensively studied using experimental and numerical methods, few studies have considered the critical role of the mining stress environment and the roof stratum in structural instabilities. In this paper, uniaxial static-cyclic loading tests were performed on a series of composite specimens with different roof lithologies. The objective is to investigate the damage and failure process of composite specimens under mining-induced stress conditions, particularly the mechanical response and damage evolution to coal and rock under cyclic disturbance. The results indicate that the mechanical behaviour of the composite specimen is closely related to the mechanical properties and interactions of the components, and the coal and rock show various characteristics of deformation and damage under cyclic loading with increasing static stress. A dynamic elastic strain energy (DESE) index based on the energy conversion of the specimen was proposed, which is more consistent with the trend of the P-wave velocity and thereby can well reflect the damage state of
