Energy Science &Engineering, EarlyView.This work reveals the “C‐Y,” double “Y,” “π,” and “Y” fracture modes of thick, hard strata and their progressive breaking process (O‐F‐R/S mode), providing a theoretical basis for controlling strong ground pressure in deep mining. ABSTRACT In response to the dynamic hazards caused by the fracture of thick‐hard strata in deep mining, this study ...

Geofluids, Volume 2026, Issue 1, 2026.Water inrush poses a serious threat to the safety and sustainability of coal mining operations, particularly in arid–semiarid regions where confined aquifers overlie coal seams. Therefore, an accurate assessment of roof water inrush risk is essential to prevent water hazards on the roof.

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 10, October 2025.Abstract Giant dyke swarms are important but enigmatic components of magma transport in the Earth and terrestrial planets. Although widely documented on Earth, Venus, and Mars as extending laterally for 100–1,000 s of kilometers from their magma sources, the reasons for this extraordinary lateral propagation are not known.
