A New Model for Calculating Voidage in Goaf Under Roof‐Cutting Pressure Relief Mining: Exploring the Influence of Volumetric Strain on Voidage From the Perspective of Finite Element

Energy Science &Engineering, EarlyView.
ABSTRACT Roof cutting and pressure relief mining technology has been applied in coal mine enterprises because of its advantages of improving the resource utilization rate. Compared to the previous longwall mining mode, the roof unloading and caving characteristics of goaf have undergone significant changes, leading to different patterns of overlying ...

Investigating the Characterization of Pore Size Distribution and Permeability, Capillary Water Absorption in Porous Media Based on Entropy Theory

Energy Science &Engineering, EarlyView.
ABSTRACT The performance of porous media, such as capillary water migration and permeability, is significantly influenced by the complexity of the pore structure. The pore complexity can be characterized by the fractal dimension of the pore structure (D f ${D}_{f}$) and the fractal dimension of pore tortuosity (D T ${D}_{T}$).

Study on the Heat Transfer Law of Coal Spontaneous Combustion in Open‐Pit Mining Benches Under Varying Wind Speeds

Energy Science &Engineering, EarlyView.
ABSTRACT The influence of external wind speed is critical for determining the spatial distribution of self‐heating zones within open‐pit mining benches. This study initially establishes the critical temperature required for the spontaneous combustion of the 13# coal seam at the Hequ Open‐Pit Mine.

Mechanism of Roof‐Cutting by Densely Drilled Holes in Gob‐Side Entry Retaining and Its Main Influencing Factors

Energy Science &Engineering, EarlyView.
ABSTRACT Roof‐cutting by densely drilled holes (RCDDH) has been widely adopted in many coal mines across China as an innovative roof‐cutting technique. However, research on its underlying mechanism and key parameters remains limited, particularly regarding the failure mechanisms of the drilled holes.
