Caving mining in extra-thick coal seams induces large-scale overburden movement, leading to more intense fracture processes key strata, significant surface subsidence, and frequent dynamic disasters mines. This study, using the N34-2 caving face of 17th seam at Junde Mine as a case aims investigate time-varying linkage mechanism between microseismic characteristics, scales overburden's strata under such conditions. Based on Timoshenko's theory, bearing mode for is proposed, corresponding criteria are established. The modes step distances working were calculated theoretically verified localization data, showing that higher prone failure, increase distances. Numerical simulations monitoring techniques employed comprehensively analyze main controlling factors subsidence. To further clarify high-position full cycle divided into four sub-processes: short-term fracture, rapid compaction stability, energy accumulation. relationship subsidence responses analyzed each sub-process, establishing system. approach offers systematic accurate method predict assess movement processes, providing new insights prevention control rock burst seams.
