Character appearance of fault structure in seismic wave CT inversion for mine work faces detecting;

The technique of "balance section" is a combination of geological thought and computer technique, which improves the research for fault structure up to quantitative stage.

To show stratum-structure in basin,a new kind of method is presented and an algorithm is provided to realize the method,which is based on some recent advancement in theory research.

Two kinds of revolutionary models for sequences including structural sequence model and climate sequence model developed in foreland basin were presented.

The structural sequences of stretch rift basin is usually composed of coarse grain sequence in the bottom,volcanic rock bearing sequence in the lower part,deep water sequence in the mid part and filling sequence in the upper part.

Integrated information about geology, geophysical and assaying, study structural sequence and sedimentary system of transition period of fault sag in Jiyang depression.

Renewing knowledge of deep structures of Dongying depression.;

The orientation and amplitude of thinning and thickening zones of main mining coal seams in some mining areas of Qianling coal mine are studied,through observation and research on the features and distribution regularities of slip sheet structures.

By relating the maximum reflectivity (R°max%) of the vitrinite to the coal seam stru-ture breakage in Sudong Coal Mine Area, the authors draw the conclusion that the increase of the maximum reflectivity of the vitrinite can be attributed to the structure breakage cuased by the slip sheet structure and the large quantity of heat resulting from it.
