| Abstract: | 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. |
