On the quantitative determination of coal seam thickness by means of In-Seam Seismic Surveys

Popis výsledku v původním jazyce

The mining at the coal mines of OKD in the Karvina Subbasin is often seriously affected by erosion [1]. As a consequence the thickness of the coal seam can considerably vary in eroded coal seam areas from small amount up to complete erosion. Because of technical and economical reason the knowledge about their location and the remaining coal seam thickness within the erosion areas is required prior to the mining of coal panels or even for its designs. The in-seam seismic (ISS) survey technique [5,6,7] isable to locate such areas as it ?looks parallel to the layering. It uses the ability of coal seams to guide seismic waves. By applying transmission surveys disturbed and undisturbed coal seam areas can be separated and by applying the reflection methodthe borders of eroded areas can be located in case of almost sudden thickness changes (for instance erosion channels)[8]. In addition by applying ISS-tomography [3] to the transmission data the coal seam structure and the remaining coal s
