Deep sublevel cave mining and surface influence [PDF]
Proceedings of the International Conference on Deep and High Stress Mining, 2017 With increasing mining depths and excavation volumes comes not only increased rock stresses and more difficult underground mining conditions, but also increased surface effects, in particular from cave mining. The surface effects of deep sublevel cave mining are not well understood and are further explored in this paper, through a case study of the ...

Cave Communities: From the Surface Border to the Deep Darkness [PDF]
Diversity, 2020 The discipline of subterranean biology has provided us incredible information on the diversity, ecology and evolution of species living in different typologies of subterranean habitats. However, a general lack of information on the relationships between cave species still exists, leaving uncertainty regarding the dynamics that hold together cave ...

Microbial communities in dark oligotrophic volcanic ice cave ecosystems of Mt. Erebus, Antarctica. [PDF]
, 2015 The Earth's crust hosts a subsurface, dark, and oligotrophic biosphere that is poorly understood in terms of the energy supporting its biomass production and impact on food webs at the Earth's surface.

Preliminary results from archaeological investigations at Sudwala Caves, Mpumalanga, South Africa
Southern African Field Archaeology, 2023 People seldom used deep cave systems during the late Holocene in South Africa. Consequently, excavations were conducted in 2010 to establish the origins of artefacts found during tourist infrastructure developments at Sudwala Caves.

Eogenetic caves in Pleistocene carbonate conglomerate in Slovenia
Acta Geographica Slovenica, 2012 This paper focuses on caves in Pleistocene carbonate conglomerates in Slovenia and for the first time defines them as eogenetic. The conglomerates show no deep burial that would resemble the mezogenetic stage of diagenesis and are still in the phase of ...

Light as a limiting factor for epilithic algae in the supralittoral zone of littoral caves
Frontiers in Marine Science, 2016 In a littoral cave system, abiotic environmental properties, such as the intensity and spectral distribution of light, often change going from the exterior to the interior part of the cave, filtering the light and thus creating a deep-sea irradiance ...
