【摘要】 随着煤炭开采机械化程度的不断提高,煤层结构的变化对采掘工作的影响日益突出。三维地震资料不仅能够控制落差3~5m以上的断层和幅度大于5m的褶曲,而且还可以利用三维资料所包含的丰富地质信息,包括煤层反射波振幅能量强弱的变化、波阻抗反演等对煤层结构的变化情况进行圈定,以提供煤层结构方面的地质资料。更多还原

【Abstract】 With continuous improvement in mechanization of coal mining,the effect of change in coalseam structure on mining has become increasingly remarkable.Three-dimension seismic data can not only be used to figure out faults with drop height over 3-5m and folding of amplitude over 5m,but also provide rich geological information,including variation in reflective wave amplitude and in energy strength,and wave impedance inversion as to locate changes in coalseam structure.更多还原
