A geological contribution to the research on mining subsidence at the Germunde coall mine (NW of Portugal)

Abstract

[Resumo] Apresenta-se neste trabalho um estudo geológico de pormenor relativo asubsidencia mineira provocada pela explora~ao de carvao na Mina de Germunde (Bacia Carbonífera do Douro, NW de Portugal). Os autores analisam e discutem os diferentes aspectos litológicos e estruturais que condicionam a localizaao das descontinuidades induzidas pela subsidencia, que afloram asuperficie do terreno.[Abstract] The aim of this paper is to present a detailed geological research of the mining subsidence induced by exploitation of the Germunde Coal Mine (Douro Coalfield, NW of Portugal). The authors analyse and discuss the different lithological and structural aspects that control the location of mining subsidence discontinuities appearing at ground surface
