巷道顶板离层临界值的确定一直是困扰煤炭行业的一大难题，也是关系到煤矿安全的重大问题。摒弃以往根据巷道具体地质和生产条件确定顶板离层临界值的方法，在锚杆支护系统本身所允许的变形量基础上，提出了基于锚杆支护系统允许的巷道顶板离层临界值确定方法，并在实验室试验和现场实测基础上，计算得出了不同锚杆长度和锚固方式下巷道顶板离层临界值。

Determining the critical value of roof separation is always a difficult safety problem for coal industry. The typical determining method considering roadway and mining condition abandoned, a new method limited by allowable deformation of anchored bolt support-ing system was present. On the basis of laboratory test and on-the-spot observation, critical values of roof separation under different an-chored bolt lengths and anchorage manners were obtained.
