摘　　要：针对“110工法”沿空留巷尾巷留巷段的底鼓治理问题,以黄陵矿业一号煤矿1009工作面为研究背景,提出采用“垛式支架+U29型曲线挡矸柱+16^(#)工字钢+C30混凝土砼地坪”复合底鼓治理方案。现场工业性试验表明,在整个监测周期范围内,底鼓量峰值达到83 mm,整体底鼓较小,巷道变形得到有效控制。In view of the problem of heavingfloor administer in the retaining roadway section of the tail roadway gob-side retaining roadway with the"110 construction method",and taking the 1009 working face of the No.1 Coal Mine of Huangling Mining Industry as the research background,the composite heaving floor administer scheme of"piled support+U29 type curve gangue retaining column+16^(#)I-beam+C30 concretefloor"is proposed.Thefield industrial test shows that in the whole monitoring period,the peak value of heavingfloor reaches 83 mm,the overall heavingfloor is small,and the roadway deformation is effectively controlled.
