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

Study on Roof‐Control Technology for Gob‐Side Entry Retaining Under Composite Roofs

Energy Science &Engineering, EarlyView.
This study develops a roof‐control technology system for gob‐side entry retaining under composite roofs. By integrating field measurements, theoretical analysis, and numerical simulation, it reveals the spatiotemporal evolution of the plastic zone and proposes a targeted support method, providing theoretical and practical guidance for safe and ...

Infrastructure‐Constrained Pathways for Large‐Scale CO2 Mitigation via CCUS in China's Coal‐Fired Power Sector

Energy Science &Engineering, EarlyView.
This study develops a multi‐objective optimization framework to evaluate large‐scale carbon capture, utilization, and storage (CCUS) deployment in China's coal‐fired power sector. By jointly considering cost, net CO2 mitigation, and system robustness under infrastructure constraints, the analysis reveals Pareto‐optimal deployment patterns and ...

Optimization of Blasting‑Induced Roof Cutting Parameters in Key Stratum and Its Application in Gob‑Side Entry Retention Technology

Energy Science &Engineering, EarlyView.
This study addresses hard roof coal seam conditions by optimizing key stratum blasting‐cutting parameters through theoretical analysis, numerical simulation, and field tests. It proposes calculation methods for blast hole spacing and delay timing based on stress wave theory, controlling roadway deformation within 35 mm, thereby enhancing resource ...
