摘要

沿空留巷作为一种能显著提升煤炭回采率的工艺手段,在国内各大矿区有着广泛应用。但随着回采深度的增加,沿空留巷的围岩控制难度不断增加,影响煤矿生产安全。以此为着手点,结合具体工程实际,在分析沿空留巷围岩控制难点与对策的基础上,对相应的沿空留巷支护技术进行了分析总结,希望能够为矿井生产的安全开展提供借鉴与参考。
        Gob-side entry retaining, as a technological means to significantly improve coal recovery, has been widely used in major mining areas in China. However, with the increase of mining depth, the difficulty of surrounding rock control of gob-side entry retaining is increasing, which affects the safety of coal mine production. Taking this as a starting point, combined with the actual engineering, this paper analyzed the difficulties and countermeasures of surrounding rock control of gob-side entry retaining and summarized the corresponding support technology for gob-side entry retaining, hoping to provide reference for the safe development of mine production.
