With minor variations, the detailed surveys below Jezerka, at Černice and Horní Jiřetín produced findings similar to those from the Jezeří survey. The mountainsides and their bases were modified by tectonic fault zones up to several dozen metres thick. Within them, the crystalline rocks were crushed or even disintegrated into a sandy-clay earth. The basin strata series at the edge of the basin were also disrupted by various fault and non-fault deformities. | With minor variations, the detailed surveys below Jezerka, at Černice and Horní Jiřetín produced findings similar to those from the Jezeří survey.

Now the problem was how the mine planners and operators would cope with that because they still insisted on their original plan to fully deplete the seam up to the edge using the large-scale opencast method, albeit at the cost of disproportionate expenses and special precautions, the technical and energy intensity of which would clearly outstrip any profit from the coal mined. | Now the problem was how the mine planners and operators would cope with that because they still insisted on their original plan to fully deplete the seam up to the edge using the large-scale opencast method, albeit at the cost of disproportionate expenses and special precautions, the technical and energy intensity of which would clearly outstrip any profit from the coal mined.[[File:CSA2.jpg|thumb|CSA2]] | ||
