Installation of Geosynthetics at the Cerro do Lobo Tailings Storage Facility Barroso, M. P.; Manso, J.; Brito, A.; Marcelino, J.; Galrão, R.; Oliveira, M. IGS-França The Cerro do Lobo Tailings Storage Facility is part of the Neves-Corvo Mine, located in Portugal. The mine is operated by Somincor, a Portuguese company and a subsidiary of Lundin Mining Corporation. The mine has been in operation since 1988 and processes copper and zinc with an annual capacity of 2.8 million tonnes and 2.5 million tonnes, respectively. The facility consists of a zoned rockfill tailings dam. The tailings storage area was recently expanded by approximately 10%. This expansion involved the construction of a new embankment in the southern area of the tailings facility. Technical assistance for the design and construction of the new southern embankment was provided by an independent and impartial research and development institute. The embankment incorporates a liner system with geosynthetic barriers. The use of geosynthetic barriers presented several challenges during both the design and construction phases. This paper discusses the main challenges faced during the construction of the liner system, mainly related to the installation of the geosynthetics.

Characterisation and diagnosis of timber floor of the Ajuda National Palace in Lisbon Fontul, S.; Mota, R.; Pereira, M. M.; Cruz, H.; Matias, L.; Duarte, S.; Mera Marques, A. This paper presents a case study of Ground Penetrating Radar (GPR) application for multidisciplinary diagnostic of timber floor of Ajuda National Palace (ANP), which was the official royal house in the second half of the 19th century. Several inspection and diagnostic techniques were used in order to detect a possible termite infestation of the wood of floors and walls. The results obtained confirmed the potential of using GPR, thermography and a multidisciplinary approach to characterising and diagnosing heritage structures. Main results and recommendations are presented herein.

Conceitos e princípios da geotecnia ambiental aplicados na recuperação do passivo ambiental de São Pedro da Cova Roque, A. J.; Monteiro, V.; Coelho, M. J. Ana Vieira; Fernando Pardo de Santayana; Roberto Quental Coutinho Com o objetivo de proceder à recuperação paisagística de uma área com topografia muito irregular, maioritariamente escavada nas escombreiras da antiga mina de carvão de São Pedro da Cova, em Gondomar, e à sua futura urbanização, foram transportados para o local resíduos produzidos pela Siderurgia Nacional da Maia entre 1976 e 1996. As autoridades nacionais autorizaram esta operação de valorização de resíduos com base na sua classificação como “claramente inertes”. Devido a dúvidas sobre esta classificação, para além de outras, a operação foi cancelada em fevereiro de 2002, cerca de sete meses após o seu início. Os alertas e as pressões, quase uma década depois, de vários setores da sociedade, locais e nacionais, para os riscos do depósito de resíduos para a saúde pública e para o ambiente, desencadearam a realização de estudos que permitissem reavaliar a perigosidade e a quantidade dos resíduos depositados. O artigo expõe os principais métodos e resultados dos estudos e os principais trabalhos que foram implementados entre 2010 e 2023, e que permitiram a recuperação ambiental e paisagística do local.
