摘　　要：针对井下沿空留巷技术落后、效率低、可靠性差的不足,提出了一种新的煤矿井下沿空留巷技术,对超前锚杆索补强支护、顶板爆破预裂技术、单体支柱加强支护等工艺方案进行了详细分析。在沁秀煤业岳城矿的实际应用表明,新的煤矿井下沿空留巷技术可靠性好、稳定性高,对提升井下沿空留巷安全性和施工效率具有极大的意义。Aiming at the deficiencies of the backward technology,low efficiency and poor reliability of gob-side entry retaining in underground coal mines,this paper proposed a new technology for gob-side entry retaining in underground coal mines,and analyzed the technical schemes such as advanced bolt and cable reinforcement support,roof blasting pre-splitting technology and single-prop strengthening support in detail.The actual application in the Yuecheng Coal Mine of Qinxiu Coal Industry Co.,Ltd.shows that the new technology for gob-side entry retaining in underground coal mines is of good reliability and high stability,which is of great significance for improving the safety and construction efficiency of gob-side entry retaining in underground coal mines.
