摘要
四川山区地形高差大、地层倾角陡、煤层薄、地质情况复杂,过去虽然经过多次探索和试验,地震勘探一直未获得成功。近年来,随着技术的发展、多道数字地震仪的引进、功能齐全的数字处理技术应用的基础上,成功地采用高密度三维地震勘探,获得了较好的地质成果,为矿井建设提供了可靠的地震地质资料。
Coal fields in the mountains,Sichuan are characterized by large difference of elevation,steep dip angle of thin coal bed and complicated geology which make the application of seismic prospecting difficult.The application of the high density 3D seismic prospecting becomes possible thanks to advance in the technique,introducing multichannel digital seismograph and advanced data processing technique.
