新疆有不少地区为戈壁砾石覆盖,地震地质条件极差。砾石区的地震工作方法,一直是应急需解决的问题。近几年来,在塔里木盆地西南坳陷地带的广阔砾石区开展了地震工作。经过反复实践,最后用“三大”的方法(大量炮坑大面积组合爆炸,大量检波器大面积组合和大炸药量)获得了深反射,基本上突破了砾石关,初步满足了地质任务提出的要求。 Many areas in Xinjiang cover the Gobi gravel, and the geological conditions are extremely poor. Earthquake work in the gravel area has always been an issue to be solved urgently. In recent years, the earthquake has been carried out in the vast gravel area in the southwestern depression of the Tarim Basin. After repeated practice, finally with the “three big” method (a large number of large blasthole explosion, a large number of detector large area and large explosives amount) to obtain deep reflection, basically broke through the gravel, preliminary meet the geological tasks proposed Request.
