摘要

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.
