【摘要】 我国煤田三维地震勘探经过20余年的发展,已成为当前煤田地质勘探的主流技术,随着煤矿采掘现代化及安全保障系统对勘探精度要求的提高,三维地震勘探技术也须与之相适应,不断地探索与发展。参考近年来相关研究成果与勘探实例,对可在煤田地质勘探中大面积推广应用的三维地震勘探技术进行了介绍,其中包括:高密度空间采样、数字检波器、高精度静校正技术、叠前时间(深度)偏移技术、分频解释技术、波阻抗反演技术、相干体技术,同时也简要介绍了在煤田勘探方面有发展前景的多分量及各向异性技术。更多还原

【Abstract】 Twenty more years development of coalfield 3D seismic prospecting in China is already a mainstream technology in coal geological exploration.Along with modernization of coalmine winning and opening,as well as increasing requirements of safeguard system on exploration accuracy,3D seismic prospecting technology should be adapted with,and kept exploring and developing.Using related research results and prospecting examples in recent years,have discribed vast popularization and application of the technology in coal geological exploration,including: high density spatial sampling,digital geophone,high precision statics,prestack time(depth) migration,frequency division interpretation,field impedance inversion and coherent body techniques.Meanwhile,multicomponent and anistropy techniques with development prospects have been briefly introduced.更多还原
