摘要
顶板离层值是一个能预测巷道稳定性的综合指标。在提出顶板离层概念的基础上,列举了顶板离层的监测形式,分析了离层的机理,并重点分析了影响顶板离层的主要因素,顶板离层临界值的确定方法及其工程应用。
The data of roof separation is considered to be a comprehensive index that can forecast the stability of roadways. This article lists the supervising forms of the roof separation on the basis of proposing its concept. It analyzes the mechanism of separation and pays much attention to the main factors that affect the roof separation, and also the definitive methods and engineering application of the critical value of roof separation.
