摘要
采用数值分析法并结合现场实际，研究了采空区压实状况对沿空掘巷围岩应力和位移的影响。研究表明，采空区压实稳定是改善沿空掘巷维护状况的先决条件。
By means of numerical analysis and the practise, this paper studies the influenceof state of stable goaf on the stress and displacement of surrounding rock of gob entry driving.The results show that the gob entry driving stabled is the first importart condition on improvingmaintain of the gob entry driving.
