The Seepage Characteristics of Single Rough Joint of Granite Based on NMR Technology: A Modified Cubic Law

Energy Science &Engineering, EarlyView.
The low‐field nuclear magnetic resonance (NMR) measurements are applied to investigate the seepage characteristics of the single rough joint. The purpose of this paper is to investigate the seepage characteristics of granite specimens with single‐joint channel under the different roughness, confining pressures and seepage pressures.

Mechanisms of Roadway Instability and Coupled Control Technology for Working Face Passing Through Fault Zones

Energy Science &Engineering, EarlyView.
This study mainly explores the instability characteristics of roadways near faults in the working face. Taking the 51104 transportation roadway of the 51104 working face in Shengxin Coal Mine as the main research object, through theoretical analysis, borehole inspection, numerical simulation and on‐site mine pressure observation, the instability ...

Control Mechanism of Pore Structure of Different Macroscopic Lithotypes on Gas Desorption Differences: A Case Study of High‐Rank Coal From the Western Ordos Basin

Energy Science &Engineering, EarlyView.
论文陈述 Paper Statement 本研究揭示了不同宏观煤岩类型的差异化控气机制:半亮煤是主要“储气核心,” 光亮煤为关键“渗流通道,” 暗淡煤则是“初期高产贡献者”。这为深层煤层气甜点优选与定制开发提供了关键理论依据。 This study reveals the differentiated gas‐controlling mechanisms of different macroscopic coal lithotypes: semibright coal acts as the primary “gas storage core,” bright coal serves as the critical “seepage channel,” and dull coal functions

Research on Crack Propagation and Stress Propagation in Coal‐Rock Combinations Under Different In Situ Stresses Subjected to Blasting Loads

Energy Science &Engineering, EarlyView.
A stress wave propagation model for coal‐rock combinations under in situ stress was established. Taking a coal mine in Huainan, China as the engineering background, isotropic and anisotropic numerical models were constructed. Field engineering practices were carried out to verify the reliability of the conclusions.
