Rock Mechanics for Natural Resources and Infrastructure Development. Invited Lectures contains the Invited and Keynote Lectures and the prestigious ISRM Award Lectures (the Leopold Muller Award Lecture by professor Peter K. Kaiser and the Manuel Rocha Award Lecture by Dr. Quinghua Lei), as presented at the 14th ISRM International Congress (ISRM 2019, Foz do Iguacu, Brazil, 13-19 September 2019). Starting in 1966 in Lisbon, Portugal, the International Society for Rock Mechanics and Rock Engineering (ISRM) holds its Congress every four years, where relevant themes related to rock mechanics and rock engineering are discussed. This volume covers topics ranging from fundamental research in rock mechanics, laboratory and experimental field studies, to petroleum, mining and civil engineering applications, and is a must-read for academics, engineers and students involved in rock mechanics and engineering. Proceedings in Earth and geosciences - Volume 5 The 'Proceedings in Earth and geosciences' series contains proceedings of peer-reviewed international conferences dealing in earth and geosciences. The main topics covered by the series include: geotechnical engineering, underground construction, mining, rock mechanics, soil mechanics and hydrogeology.
