摘要:
为了积累高台阶抛掷爆破时地震效应的经验，采用MiniMate Plus爆破地震仪对黑岱沟露天煤矿第一次高台阶抛掷爆破产生的地震效应和爆破噪声进行了监测，详细地分析了爆破地震波和爆破噪声的强度、频率、持续时间等特征参数。分析结果表明，本次爆破对矿区周围的被保护对象不会造成破坏，并可以利用仪器记录爆破地震波和爆破噪声起始时间的差值，计算出岩体的纵波速度。研究结果对该矿山后续的高台阶抛掷爆破的设计具有参考价值。
Abstract:
In order to accumulate the experience of explosive seismic effect of high bench cast blast, MiniMate Plus blast seismograph is used to monitor on the explosive seismic effect and explosive noise of the first high bench cast blast of Hei Daigou Surface Coal Mine. The characteristics parameters of intensity, frequency and duration of both explosive seismic wave and explosive noise are detailedly analysed. The analysis result makes it clear that it is impossible for the protected objects around the mining area to be destroyed, and the longitudinal wave velocity of mass rock can be calculated with the beginning record time difference between explosive seismic wave and explosive noise. The research result sheds light on the following designs of high bench cast blast of the Hei Daigou Coal Mine.
