Research on the Distribution of Overlying Rock Fractures Caused by Mining in Ultra-Thick Coal Seams and Its Impact on the Near-Surface Aquifer

Yang Zhou,
Xueyi Yu

Abstract: Near-surface water is the foundation for maintaining the ecological environment, and coal remains an important energy source in today’s world as we face a shortage of green energy. Achieving near-surface-water protection while safely mining coal is an important way to ensure social and ecological health and sustainability. The key lies in whether the fracture height of the mining overlying strata affects the aquifer. This article compiles the coupling finite element and discrete element method (CFE-DEM) and es… Show more
