从一九七四年十一月至七五年六月,数字地震会战指挥部有六个队采用数字地震仪在J—J和DY地区开展了野外工作方法试验,并在六个二级构造带的十二个局部构造上完成了60条测线的剖面测量。这是我国第一次大规模地在陆上应用数字地震勘探技术。通过会战掌握了数字地震仪的野外工作方法,并取得了明显的地质效果。 From November 1974 to June 1975, six teams from the Digital Earthquake Headquarters conducted digital field tests of field work methods using digital seismographs in six secondary structures Sixty lines of profile measurements were completed on the twelve local structures of the belt. This is the first large-scale application of digital seismic exploration technology on land in our country. Through the battlefield mastered the digital seismograph field work methods, and achieved significant geological results.
