Research on the influence of pits on the propagation law of explosion shock waves [PDF]
Scientific ReportsTo study the influence of pits on shock wave propagation and the propagation of shock waves within pits, numerical simulations were used to calculate the distribution of overpressure peak values at the bottom and rear of the pits at 5 depths and 5 ...

USING DEEP LEARNING AND HOUGH TRANSFORMATIONS TO INFER MINERALISED VEINS FROM LIDAR DATA OVER HISTORIC MINING AREAS [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2020 This paper presents a novel technique to improve geological understanding in regions of historic mining activity. This is achieved through inferring the orientations of geological structures from the imprints left on the landscape by past mining ...

Lunar Pit Craters Presumed to be the Entrances of Lava Caves by Analogy to the Earth Lava Tube Pits [PDF]
Journal of Astronomy and Space Sciences, 2014 Lava caves could be useful as outposts for the human exploration of the Moon. Lava caves or lava tubes are formed when the external surface of the lava flows cools more quickly to make a hardened crust over subsurface lava flows.

Multidisciplinary analysis of pit craters at Hale Crater, Mars
Icarus, 2023 Pit craters are circular to subcircular depressions that lack a rim and ejecta layer and typically have a conical shape. There are several mechanisms that can explain the formation of such depressions and they are associated with collapse due to the removal of subsurface material. Possible origins of pit craters include: volcanic processes (collapse of

Crater effects of shallow burial explosions in soil based on SPH-FEM analysis
Frontiers in Earth Science, 2023 This study analyzed the effects and influencing factors of shallowly-buried explosions in soil based on the design and implementation of static explosion experiments and numerical simulations. Based on the static explosion test data, a numerical analysis

Unconventional filling dynamics of a pit crater
Earth and Planetary Science Letters, 2021 Abstract The rise and fall of magma columns is a process commonly observed in volcanoes hosting lava lakes and serves as proxy of magmatic reservoir pressure and warning for potential eruptions. This dynamic process typically involves the filling and emptying of a “pit crater” - a cylindrical depression usually formed by one or more collapses of a ...

Method for Identifying Lava Tubes Among Pit Craters Using Brightness Profile Across Pits on the Moon or Mars [PDF]
Journal of Astronomy and Space Sciences, 2016 Caves can serve as major outposts for future human exploration of the Moon and Mars. In addition, caves can protect people and electronic equipment from external hazards such as cosmic ray radiation and meteorites impacts and serve as a shelter ...
