摘要： 针对坚硬顶板垮落造成沿空留巷围岩变形大的问题，采用高水材料对沿空留巷进行充填，借助对安全缺口和
巷道的加强支护完善了支护方案。对巷道顶板的受力变形、锚杆受力和充填体承载状况进行监测，相关监测参数表明，
沿空留巷受力变形均在安全范围内，证明了方案的可行性。

Abstract: Aiming at the problem of large deformation of the surrounding rock of the gob-side entry retaining caused by the collapse
of the hard roof, high-water materials were used to fill the gob-side entry retaining, and the support scheme was improved by
means of the reinforcement of safety gaps and roadways. The stress and deformation of the roadway roof, the stress of the bolt and
the bearing condition of the backfill were monitored. The relevant monitoring parameters showed that the stress and deformation of
the gob-side entry retaining were all within the safe range, which proved the feasibility of the scheme.

Key words: gob-side entry retaining; bolt's stress; filler
