摘　　要：TSP探测已成为隧道超前地质预报最为重要的一个手段。笔者结合实际工作,对TSP203型探测仪在雷管、炸药的使用,数据处理滤波窗口的选择,隧道管波的消除等问题进行了讨论,如采用延时触发雷管保证数据采集的同步性,改造调整触发系统;调整炸药量,改进封装;采用带通滤波,压制管波等。这些应用手段可供其他使用者借鉴。TSP detection has been one of the most important means of geological prediction. According to the practical engineering experience on TSP203, this paper discusses some problems concerning TSP data acquisition and processing, such as the adoption of delayed trigger of detonator to guarantee the synchronism of data acquisition, the reformation and adjustment of the trigger system, the adjustment of explosive quantity, the improvement of package, the adoption of bandpass filter, and the suppression of pipe wave. These application means can serve as reference for other users.
