摘要
巷道围岩变形率预测是巷道支护设计的主要环节，本文以影响回采巷道稳定性的主要因素为基础，分析整理了我国煤矿１００多条典型的巷道实测数据，应用多元线性回归方法，建立了预测各类巷道围岩变形率的回归方程，经理论检验与实例验证，预测方法可用于我国回采巷道控制设计，具有广泛的实用价值。
The prediction of displacement rate in surrounding rock of face entries is amain link of the entry supporting design. This paper,based on the major factors affecting thestability of face entries,analysed and sorted out the observation data of more then 100 typicalentries By using polybasic regression method,we derived a set of regression equations used topredict the displacements in the surrounding for all kinds of roadways.It has been verifed bytheories and examples that this kind of forecasting method has extensive and practical valuein the supporting design of face entries.
