Abstract
To master the overburden structure failure and fracture evolution law under multi-key stratum control during repeated mining in coal seams, this study takes the superimposed mining faces of 6# and 7# coal seams in Xinjiang mining area as the research background. Through comprehensive research methods including theoretical analysis, similarity simulation, numerical simulation, and field monitoring, it systematically reveals the evolution law of overburden fractures under repeated mining controlled by multiple key strata, and clarifies the crucial control effects of cumulative damage in the overburden and the superimposed effect of mining-induced stress fields on fracture morphology during repeated mining of…
