摘　　要：为了对井壁安全进行合理评价,及时开展井壁的维护和治理工作,利用灰色系统理论的GM(1,1)模型,将监测到的附加应变数据视为灰色量,运用数列方法进行数据生成、拟合和预报。结合某矿实际监测数据进行预测分析,实践表明,该模型具有较高的拟合和预测精度,采用灰色预测方法对井壁附加应变进行预测是可行的。Aimed at rational evaluation of the stability of the shaft wall and the timely maintenance and control of the shaft wall, this paper features a Grey System Theory GM （ 1 , 1 ） -based model on which the additional strain-related data obtained from the handling shaft wall breaking are regarded as gray variables, and data are generated, fitted and predicted with the sequence method. The analysis, combined with the actual monitoring data, shows that the model with a better fitting and forecasting accuracy proves feasible for predicting the additional strain of the shaft wall.
