摘　　要：本文以ＤＫＪ－１型矿压计算机监测系统在两个矿的顶板来压监测和预报实际资料为依据，深入分析了８个月，１３次来压的支承压力显现规律，并将显现形式分为“压缩反弹型”和“波动型”两种类型，总结了显现的特征参数及与来压的时间差和位置差。文章介绍了计算机监测系统识别来压前兆的方法及准确预报１３次来压的良好效果。Based on the numerical data of roof weighting monitoring and forecasting recorded by DKJ-1 mine pressure computer monitoring system in two coal mines the authors analysed thoroughly the law of abutmant pressure manifestations of 13 roof weigthings within 8 months.The abutment pressure manifestations can be distinguishedd into two types,the'compression-rebound' and'fluctuation'types,and their relation,the time difference and position difference of roof weightings are summarized.In this paper,the authors also introduce the method ofrecognizing roof weighting omen by the computer monitoring system and the excellent result of 13 roof weighting fore-casts was accurately obtained.
