一、用地震探测系统寻找井下被困矿工地震探测系统使用一组灵敏的地音探测器,将它们放在被困矿工可能停留的区域之上。预先使矿工学会以某种方式敲打顶板或煤(岩)邦来发出地震信号。根据地音探测器的排列方式,地震信号到达每个地音探测器的时间是不同的。接收到的信号贮存在现场测量仪器车的磁带中。车上还装有处理信号用的其他高级设备。收到的信号用小型现场计算机或以电话线输入到更大功率的计算机加以分析,并根据分析结果来确定地震信号源的位置。图1示明了该系统的检
First, the use of seismic detection system to find miners trapped Downhole seismic detection system uses a set of sensitive ground sound detectors, put them in the trapped miners may stay above the area. The miners were informed in advance to signal the earthquake by knocking the roof or coal in some way. Depending on how the geophones are arranged, the time at which the seismic signal reaches each geophone differs. The received signal is stored in the tape of the field measuring instrument car. The car is also equipped with other advanced equipment for signal processing. The received signal is analyzed using a small field computer or by telephone line to a more powerful computer and the location of the seismic source is determined based on the analysis. Figure 1 shows the system check
