The basic framework of coalfieldstructure was settled under SE-NW directional compression during Late Mesozoic.
中生代晚期SE-NW向挤压,奠定煤田构造格架的基础;

Coalfieldstructure was controlled by NNE structure. Coal bed structure thinning belt was also extended in NNE directions, Southern Hebei coalfield.
煤田构造主要受北北东向构造所控制,其煤层构造变薄带也主要呈北北东向伸展。

The results demonstrated that this technology can improve imaging of coal seams in structure complicated areas and coalfield seismic data signal-to-noise performance and resolution effectively.
