本文主要讨论地震地质条件和激发条件。根据相对的和发展的概念,提出了地震地质条件的难易是随着勘探的目的和对象的改变而发展的。在有的勘探区中,浅层条件是主要的困难,而浅层条件中,激发条件又是最重要的。为了获得高讯噪比的记录,本文阐述了在中等速度层中激发与合理地选择震源参数的重要性。

The article mainly deals with the explosive and seismic geological conditions. In this paper, the author has put forward a new idea that the "favourableness" or "unfavourableness" of the seismic geological conditions is not an absolute concept but a relative one. In fact, it always changes with the aim, the object and the means of the exploration. In some of the exploring regions,the main points that should be taken into account are the shallow conditions and to them, the most important thing is the explosive condition, To improve the signal-to-noise ratio of the record it has been proved that the thing of great importance is to explode in a medium-velocity stratum and to select the source parameters properly.
