摘要
为掌握沿空巷道留巷围岩活动规律,巷旁充填体的受力与变形规律,分析沿空留巷效果。该文对沿空留巷期间巷道变形、顶板离层及锚杆受力情况进行监测;观测结果表明:沿空巷道留巷期间是稳定的,支护效果良好,能够满足生产需要。
To master the law of surrounding rock activity in gob-side entry retaining, and roadside filling body stress and deformation and analysis the effect of gob-side entry retaining. This paper monitors roadway deformation, roof separation and the force of the bolt during gob-side entry retaining; The observation results show that gob-side roadway is stable, good support effect and can meet the needs of production during entry retaining.
