本文介绍了两种利用物探技术进行地质超前预报的方法 ,即地震负视速度法 (测试面与被探测面互为垂直的观测系统 )及地震横排列法 (震源孔和接收孔分别位于掌子面两侧的侧壁上 ,有规律地横向排列 )的原理及测试方法 ,文中还介绍了两个工程实例 In this paper, we introduce two methods of geophysical prediction using geophysical prospecting, ie, the method of seismic negative velocities (the observation system whose test surface is perpendicular to the surface to be detected) and the method of seismic horizontal arrangement (the source hole and the receiving hole are located on the palm Surface on both sides of the sidewall, a regular horizontal arrangement) principle and test methods, the article also introduced two engineering examples
