摘要: 依据某开采区的勘察资料,建立了采空区稳定性预测的距离判别模型,选取影响采空区的主要因素作为判别因子,以实测样本作为训练样本,建立相应的线性判别函数对待判样本进行分类。研究结果表明,距离判别分析模型是采空区预测的一种有效方法,可以在实际工程中应用。

Abstract: Based on the investigation data of a mining area, a distance discriminant model of stability prediction of goaf was established. Some main factors which influence goaf were selected as discrimination factor, then it took measured sample as training samples, discriminantwaiting sample was classified by establish corresponding linear discriminant function. Study result indicates that distance discriminant analysis model is an effective method of goaf prediction which could be used in practical engineering.

Key words: Goaf, Prediction, Distance discriminant analysis
