Exploring Low‐Global Warming Potential Refrigerants for Medium‐Charge Systems

Energy Technology, EarlyView.
This study evaluates 15 low‐global warming potential (GWP) refrigerants as alternatives for medium‐charge systems, focusing on environmental impacts, operational performance, and system design integration. Key findings reveal R‐447A's suitability for standard climates and R‐454B's advantages in high ambient conditions, providing actionable guidance for

Damage Characteristics and Parameter Sensitivity of Fracture Caverns Under Pneumatic Disturbances

Energy Science &Engineering, EarlyView.
ABSTRACT In the construction process of abandoned mine compressed air energy storage projects, the presence and distribution of fractures within the rock mass significantly influence both the design and safe operation of the energy storage system. To investigate how initial fractures affect rock mass damage under pressure disturbances, a coupled model ...

Porosity Optimization Model to Characterize Gas Seepage Behavior in Longwall Mining Gobs: An Application Case and Simulation Analysis

Energy Science &Engineering, EarlyView.
ABSTRACT The degree of fragmentation of coal rock determines the porosity distribution of goaf porous media, which can be expressed using empirical formulas. However, this method fails in regions with nonuniform caving, dynamic disturbances, or deep high‐stress conditions. Therefore, this study developed a porosity optimization model comprising A and B

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 ...

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.
