Abstract This work in Xingdong Mine 1200 Area is focused on use of the basic documents of seismic, logging and site disclosure and the results of comprehensive geological research. Based on Petrel geological modeling platform, applying the advanced spectral decomposition and Ant-Tracking technology, taking Xingdong Mine 1200 Area as an example, the large, medium and small-scaled discrete crack network models are established. It has also made reconstruction and realized the effective prediction of the fault system and Collapse-column, which provided a solid fundamental guarantee for the prediction of faults and complex geological body in other regions.

1 Introduction In coal mining process, collapse column, minor fault and fracture are the serious issues need to be addressed to avoid hydrogeological hazards. Especially for the mines under large mining depth and high confined situation in North China Type Coal Field, which coal seam floor bears high water pressure. 3-D seismic technology is rapidly expanded and applies in many mine areas for its advantage which is with less investment, high precision, quick results, and it has taken place of the traditional geological prospecting methods as an indispensable method in coal mine production. With the exploration of deep coal resource, the existing structure interpretation of seismic exploration becomes gradually unsatisfactory to the

demand of control accuracy which is required by mine area production. This paper processes post-stack seismic data by spectral processing technique taking geological data, borehole data and on-the-spot exposure data as constraint conditions, to obtain discrete phase target data as the simple of Xingdong Mine 1200 Area. At the same time the study tries to use the Ant-Tracking to track target layer automatically and then verify the efficiency and applicability of comprehensive interpretation based on spectral decomposition and Ant-Tracking by summarized after mining.
2 Theory and Method Theoretically, the high frequency component of seismic data is sensitive to micro-fault or micro-deflection. So we can explore the micro-fault or microdeflection using high frequency component of seismic data. Spectral decomposition technology uses S-transform which can generate high resolution spectral decomposition image to calculate. Using spectral decomposition, the Ant-Tracking technique can automatically explore the small faults and fractures which is difficult to identify in the whole bandwidth seismic data [1].
