为保证西沙河煤矿残采短壁孤岛面沿空掘巷围岩的稳定，以西沙河煤矿2402回采巷道为背景，运用理论分析及数值模拟的方法，分析了沿空巷道围岩控制机理，针对合理的煤柱宽度进行理论和数值模拟分析，并提出了残煤短壁面沿空掘巷支护参数。
為保證西沙河煤礦殘採短壁孤島麵沿空掘巷圍巖的穩定，以西沙河煤礦2402迴採巷道為揹景，運用理論分析及數值模擬的方法，分析瞭沿空巷道圍巖控製機理，針對閤理的煤柱寬度進行理論和數值模擬分析，併提齣瞭殘煤短壁麵沿空掘巷支護參數。

Taking 2402 mining roadway in Xishahe coal mine as the research background ,employed theoretical analysis and numerical simulation to investigate the control mechanism for roadway driving along gob so as to ensure the stability of roadway and facilitate the extraction of residual coal at island coalface with shortwall mining. Studies were also performed to probe into the reasonable width of the narrow coal pillar. Final support parameters were proposed to control the roadway.
