| 摘 要： | 本文分析了“DKJ—1—D”声发射子系统在坚硬顶板条件下周期来压声发射前兆特征,结果表明,在老顶周期来压前,声发射将出现两次明显的波峰段,因而可以由此前兆来预报老顶周期来压,这对指导煤矿安全生产具有重要应用价值。

| Abstract: | It analysed the acoustic emission omen of periodic weighting of the hard mainfool when "DKJ-1-D" acoustic emission sub-system is tested, the results showed that it could appear two obvious wave crest sections before periodic weighting of the main foof, there fore, we can predict the oeruiduc weuggtubg if naub roof making use of the omen. It has an in portant practice value to guide the safe production coalmines. |
