| 摘 要： | 某矿山露天转地下开采过程中，由于岩体受力发生变化导致微震事件发生，因而需要对岩体进行微震监测。结合微震事件发生在矿山开采环境过程中的特点，分析了微震信号典型波形以及开采环境引起的干扰波形特征，将微震监测接收到的波形进行滤波处理，并建立了各类波形数据库，准确识别并接收采集微震信号，将其应用到露天转地下矿山开采工程项目中，可为矿山开采生产安全运营提供保障。

| Abstract: | During the process of open-pit mining to underground mining in a mine，the microseismic event occurred due to the change of rock mass stress，so it is necessary to carry out microseismic monitoring on the rock mass.Combined with the characteristics of microseismic events occurring in the mining environment，the typical waveforms of microseismic signals and the characteristics of interference waveforms caused by the mining environment are analyzed，the waveforms received by microseismic monitoring are filtered，and various waveform databases are established to accurately identify and receive the microseismic signals，which can be applied to the open-pit to underground mining project to provide guarantee for the safe operation of mining production. |
