摘　　要：针对厚煤层综放工作面沿空留巷围岩控制难题,以S1308工作面为研究对象,模拟分析了沿空留巷期间的围岩应力演化规律,提出了S1308运输顺槽沿空留巷强化控制技术方案。现场应用效果表明:采用强化控制方案后,沿空留巷两帮内移量降低至400 mm以内,取得了显著的应用成效。In response to the difficult problem of controlling the surrounding rock of the gob-side entry retaining in thick coal seam fully mechanized top coal caving working face,taking S1308 working face as the research object the stress evolution law of the surrounding rock during the goaf retention period was simulated and analyzed,and a strengthened control technology scheme for the gob-side entry retaining of the S1308 belt groove was proposed.The on-site application effect shows that after adopting the strengthened control scheme,the inward displacement of the two sides of the goaf is reduced to within 400 mm,achieving significant application results.
