The corridor of Ervěnice (EC - Seestadt corridor). The construction and consolidation of the earth dump body in variable stability conditions in the mining areas of the quarries "Jan Šverma" and "Czech Army" - Part I

Ing. Evžen Pichler, CSc., Ing. Jaromír Fultner, Ing. Petr Valvoda

The first part of this two-part´s article has seven chapters, describing the reasons for the design and construction of the "Ervěnice corridor" (EC or EK in the Czech language) - of the earth dump body with the height over 130 m and the length of approximately 5 000 m. The corridor was built by the mining way from the non-compressed clay in the years 1957-1984 and its main significance lies in the road and railway connection between industrial agglomeration and the cities Most and Chomutov. In the years 1981-1984, the important links were localised on its top: the railroad Most-Chomutov, road I/13, and then pipe bypass of the Bílina River. The first two chapters indicate the reasons for the design of the EC and its importance for mining and transport links. The chapters 3 and 4 analyse the basic conditions the high dump construction applied in the building of corridor. The chapters 5 and 6 describe the physico-mechanical properties of the rocks used in the individual dump levels. The last chapter 7 presents the results of the initial measurement of the housing settlement.
