Predecessors have made a lot of Jobs of geology and geophysical prospection to look for coal in the east side of the Song Liao depression. It is an M'area with higher research degree. In recent years the breakthrough has been made on the looking for coal in this area with the constantly deepening of geological job and cognition. The discovery of the Yangcaogou coal field fully shows that not only detailed jobs need to be done in the areas with lower research degree, but also some geological problems need deep research and recognize again in the above araes with higher research degree. In this paper, by means of remote sensing technique combining with the data of geology and, geophysical Prospection the author divides the structural framwork in this area again, masters the laws of the basement fault controlling coal basin and coal measure strata, the photographic characteristic of hidden coal basin, and carries out synthetic analysis on the known coal basin with higher:research degree, discovers the correlation between the collected coal centres. in the basin and photograph, thus establishes the structural model of collected coal, reaches the aim of forecasting unknown coal basin in research area and forecasting the new center of collected coal in basin.
