Energy Science &Engineering, Volume 14, Issue 4, Page 1851-1863, April 2026.With the advancement of coal mining technology driving the development of working faces toward increased mining heights and extended lengths, the enlargement of face dimensions has led to expanded overlying strata failure zones and intensified ground pressure manifestations. Consequently, traditional methods for determining hydraulic support resistance

Energy Science &Engineering, Volume 14, Issue 4, Page 1864-1880, April 2026.This study reveals the temporal and spatial evolution law of roof separation under the karst aquifer and the dynamic water inrush mechanism of roof separation. The FAHP–EWM–CRITIC combination weighting method was established to obtain the risk zoning of bed separation water inrush in a karst landform mining area. ABSTRACT Coalfields in northern Guizhou

Research on gas drainage drilling parameters and nitrogen injection for fire prevention in goaf
Gong-kuang zidonghua, 2020 Drilling and drainage can affect movement of air flow in goaf, thus leading to changes in goaf flow field, and increasing air leakage in goaf. At the same time, there is a state of negative pressure around the borehole, and the air leakage and air flow ...

Energy Science &Engineering, Volume 14, Issue 4, Page 1881-1902, April 2026.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 ...
