摘要
本文分析了“DKJ—1—D”声发射子系统在北京矿务局木城涧矿千军台坑坚硬顶板条件下的监测试验结果,初步探讨了老顶周期来压和直接顶初次垮落期间的声发射特征,并提出了用声发射预报来压的可行性及方法;这对指导煤矿安全生产具有重要的应用价值。
This paper analysed the experimental results of applying the DKJ-I-D Acoustic Emission Subsystem in the Qianjuntai pit of the Muchengjian Coal Mine, Beijing Mining Bureau, under hard roof conditions; preliminarily investigated the characteristics of acoustic emission during periodic weighting of the main roof and the first caving of the immediate roof; and put forward a feasible method for predicting roof weighting from acoustic emission. These would be of important practical value when used to guide the safe production in coal mines.
