A Geomechanical Study of the Mississippian Boone Formation [PDF]

, 2013
The Boone Formation in northwest Arkansas is a chert-limestone sequence analogous to the subsurface Mississippi Lime reservoir in parts of Oklahoma and Kansas. It has low permeability and produces via horizontal drilling and hydraulic fracturing.

Snow avalanche hazard of the Krkonoše National Park, Czech Republic

Journal of Maps, 2017
This paper presents a snow avalanche hazard map of the most avalanche-prone mountain range in the Czech Republic, the Krkonoše Mountains. The map was prepared using historical records of 1132 avalanches which occurred over the last 54 years and state-of ...

A study of the compound evaluation for geophysical explorations by self-organizing maps [PDF]

, 2011
In Japan, in the high economic growth period in 1960’s, a great number of cutting ground and embankment slopes were formed to construct many roads. They have been aging now, it is important to estimate the health of them and maintain effectually.

AE-based classification and fracture process analysis of flawed marble with stress intensity factor validation

Scientific Reports
The stability of rock masses is critically influenced by pre-existing cracks, yet the micro-mechanisms governing cracks evolution under varying crack geometries remain inadequately quantified. This work introduces a novel, rock-specific acoustic emission
