| 摘 要： | 为了探究强矿压前兆信号特征，基于微震和电磁辐射技术研究了峻德煤矿三采区北17层四区一段工作面的矿压显现规律，最终得到了工作面回采期间的强矿压信号特征，日震动能量和日震动次数都维持在较高水平时，代表强矿压显现的征兆，电磁辐射的脉冲值和强度都很小，说明即将有大能量释放，即为强矿压显现的前兆信号特征。

| Abstract: | In order to explore the precursory characteristics of strong tremor,based on the microseism and electromagnetic radiation technologies,tthe law of tremor appearance in the first section of the working face,which locates in the north No.17 seam of the third mining area of the Junde Coal Mine is studied,the strong tremor characteristics during the mining period of the working face is obtained.When the daily vibration energy and the number of events are maintained at a high level,it represents the symptom of strong tremor appearance and the pulse of electromagnetic radiation.Both impulse value and intensity are very small,indicating that there will be a large energy release soon,which is also the precursory signal of strong tremor. |
