Energy Science &Engineering, EarlyView.This study systematically investigates the fracture development mechanisms of water‐isolating soil layers under the coupled effects of repeated mining and groundwater seepage during the downward mining of shallow‐buried coal seams. The findings provide a theoretical basis for evaluating stratum stability and preventing roof water inrush.

Design of Initial Mining Pressure Relief Scheme for Large‐Size Mining Face: A Case Study
Engineering Reports, Volume 8, Issue 4, April 2026.The numerical simulation analysis method is used to compare the actual mining face (315 m) with the designed mining face (200 m). The results show that the large mining height working face has larger abutment pressure peak and stress concentration factor than the general mining height working face.

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
