摘　　要：介绍了TSP超前预报系统实现预报的基本原理。从基本原理出发分析了TSP对不同岩性地层的适应性问题;通过实例分析了TSP在不同地层中的预测效果。结果表明当围岩中没有大的不良地质体时,TSP在软岩中的预测效果较差,而在硬岩中预测效果好。The basic principles of the TSP advanced forecast system are introduced first, and then the flexibility issues of the TSP system when applied to different lithology strata are analyzed based on the basic principles. The forecast efficiency of TSP in different strata is also analyzed through practical examples. The results indicate that the forecast efficiency of TSP in soft rock is worse than hard rock when there are not large size ill geological objects in strata.
