在阿尔伯达丘陵地带所做地面炸药震源试验表明,通过设计震源组合图形和组合内的起爆位置,可以较大地改进地面放炮获得的资料质量。采用十字结构震源获得的多次覆盖剖面说明,在阿尔伯达逆掩断层带,用地表震源可以得到优质地震资料。
Earth-borne dynamite tests conducted in the Alberta hilly terrain have shown that the quality of the data obtained by surface blasting can be greatly improved by designing the combination of focal point patterns and the initiation position within the combination. Multiple cross-section profiles obtained using a cross-structure source indicate that high-quality seismic data can be obtained from surface sources using the thrust shield in Alberta.
