摘要
千秋煤矿为冲击矿压高发矿井,该矿引进电磁辐射仪对21141和21201两个工作面进行检测,通过对近期多次冲击发生时段电磁辐射强度变化情况分析,得出了千秋矿冲击矿压的电磁辐射前兆规律,为该矿之后的冲击矿压预测预报工作提供了参考依据。
Qianqiu Colliery is a serious rock-burst mine.Electromagnetic radiation instrument was introduced into 21141 and 21201 mining face.Electromagnetic radiation rules for forecasting rock-burst were obtained by analyzing electromagnetic radiation variation at recent rock-burst time.This provided reference for later rock-burst forecast.
