Study On The Effect Of Wave Field Phenomena On Seismic Interpretation Of Collapse Column

In North China Coal collapse column is a common geological disastersbody, its presence not only destroyed the coal seam continuity, but also easilylead mine roof fall, gas outbursts, sudden water and other accidents. Its seriousthreat to efficiently mine production safety. Therefore, in the coal mine designand production process, to identify and delineate collapse column position isvery important.Seismic exploration collapse column is more effective method of numerouscollapse column exploration methods. But its precision collapse column can notreach coal mine exploration geological tasks, the main reason is there are stillsome problems collapse column on seismic interpretation. Because in theprocess of coal mining small graben, small syncline, goaf and collapse column,in seismic wave field has a certain similarity, often resulting in misconceive, cannot accurately identify, so research the impact seismic interpretation collapsecolumn phenomenon Wave Field is necessary, it can improve the accuracy ofinterpretation of collapse column, better service coal mines.The paper summarizes the graben, syncline, goaf and collapse column, in geological characteristics, and then expounded the principles and resolutionseismic exploration concepts, and then from the principle of analyzing seismicexploration graben, syncline, goaf and collapse column feasibility, and describessome of the special geological phenomena on the four-wave seismic timeprofiles generated. On this basis, the establishment of four kinds of geologicalphenomena related to seismic and geologic model, using Tesseral-2D forwardmodeling software for different sizes of graben, syncline, goaf and collapsecolumn elastic wave equation forward modeling, comparative analysis of theirstacked section and offset sectional, combined with the actual seismic datacomparative. The results show that under this article has given model andparameters, the summary results of the seismic wave field similarities anddifferences of four geological phenomena as well as their transversal resolution.Achievements made compliance with the principles of thesis and actual, andtherefore the seismic data interpretation, with some guidance and reference.
