The current methods of 3D seismic data interpretation are based on 2D seismic data interpretation methods.

Since the dry and thick loess overburden has loose structure and without groundwater level,so it has strong absorptivity to seismic waves and very hard to carry out 3D seismic prospecting,especially in hilly ground shallow buried coal areas.

Contrast 3D seismic prospecting interpreted results and mining block practical revealed geological anomalies have found rather poor effects of early stage conventional interpretation technological means under complex seismic-geologic conditions are hard to meet requireme.

Rely on the "Western China Coal Resource High Precision 3D Seismic Prospecting Technology" project engineering,carried out high density 3D seismic prospecting aim to improve minor fault,small subsided column exploration ability.

To overcome existing puzzles in 3D seismic prospecting such as geophone layout,geophone coupling,shotpoint selection etc.

According to the example of 3D seismic exploration for coal mineral in Jiahe,Xuzhou area,discusses the difficulties to execute 3D seismic exploration and the techniques to solve these problems under the condition of deeply-mining.

The seismic information of“blank area”have been gotten, and some experience in the 3D seismic exploration under the similar condition have been gained using this method.

In view of such phenomena as complex surface conditions,shallow target formation depths and overlying Gobi and hills encountered by 3D seismic exploration in a certain coal mine of Tacheng area,Xinjiang,this paper deals with some corresponding technical measures and their geological effects at different stages of field data collection,data processing and data interpretation.
