摘　　要：在资源勘探中,由于煤田目的层埋深较浅,地表的起伏引起的静校正量对于煤田勘探影响较为严重;而且煤田勘探主要是寻找断层、陷落柱等小构造,这就对静校正提出了更高的要求。因此,针对煤田勘探复杂地表的静校正问题显得尤为重要。通过对模型正演记录和实际资料进行层析静校正量计算,有效地消除了复杂地表的影响,得到了较高质量的叠加剖面。In the exploration of coal resources, the static caused by the shallow target depth and the rolling ground influences the coalfield seriously, and coal exploration is mainly focused on faults, collapse columns, and other small structures, which sets higher demands on static correction. Therefore, the static problems which aim at tackling complicated surface in coalfield exploration are espe- cially important. The authors calculated the tomographic static of the forward modeling data records and the actual data and, as a re- suit, the influence of complex surface was eliminated effectively, resulting in the obtaining of high - quality stack profiles.
