Three-dimensional seismo-tectonics in the Po Valley basin, Northern Italy [PDF]

open access: yes, 2015
The Po Valley (Northern Italy) is a composite foreland-foredeep basin caught in between the Southern Alps and Northern Apennine mountain belts. By integrating the 3D structural model of the region with the public earthquake dataset, the seismo-tectonics ...

An optimizing microseismic method for rock burst early warning based on mining production process

open access: yesDeep Underground Science and Engineering, EarlyView.
A classification early warning method of rock burst based on hourly microseismic data is proposed, which can be combined with the on‐site production process to provide more timely warning. Abstract Microseismic (MS) events have been reported in nearly every coal mining country, which could well lead to rock burst in underground coal mines.

Development characteristics and prediction model of the water-conducting fractured zone in typical mining-induced structural overburden in the mountainous areas of Southwestern China

open access: yesFrontiers in Built Environment
IntroductionIn mining areas of the mountainous regions of Southwestern China, the overlying strata above goafs are mostly thick bedrock with well-developed structural planes. With large-scale exploitation of mineral resources, extensive water- conducting

Motion planning and control of an installation robot for attitude adjustment of arc parts in underground shield tunneling

open access: yesDeep Underground Science and Engineering, EarlyView.
Inspired by spiders, the multilegged walk‐through assembling robot for arc parts achieves high‐precision synchronous control under heavy loads through dual‐layer hydraulic pose dynamics modeling and hierarchical pressure optimization, significantly enhancing shield tunneling assembly efficiency and precision.

Fault slip-rate variations during crustal-scale strain localisation, central Italy [PDF]

open access: yes, 2002
Rates of plate motion are generally uniform over 10–102 Myrs timescales. Faults between tectonic plates might, therefore, be expected to show temporally-uniform slip-rates if the same number of faults remain active. For an extending region of the Eurasia-

Semi‐analytical solution for the stability of deep vertical shaft considering time‐dependent rock‐structure interaction

open access: yesDeep Underground Science and Engineering, EarlyView.
A novel cavity contraction solution and multilayer shaft wall model were developed to analyze deep shaft stability, considering rock viscosity, support structures, and water pressure, with successful validation through a Hulusu Coal Mine case study.

Active Tectonics and Alluvial Rivers [PDF]

open access: yesEos, Transactions American Geophysical Union, 2000
Active tectonic processes may affect the use of river resources slowly by tilting or deforming a rivers slope, changing a rivers pattern, or causing the formation of lakes that will affect river navigation and flood control. Deformation during earthquakes may suddenly change a rivers course and gradient.

Multiple injection techniques to stimulate complex fracture networks in coal reservoirs: A case study on gas disaster reduction of subsurface coal mine in southwest China

open access: yesDeep Underground Science and Engineering, EarlyView.
An experimental device for physical simulation of hydraulic fracturing, comprising: a load‐bearing mechanism with multiple interconnected plates that collectively form an sample chamber; a load‐generating mechanisms, with multiple load‐generating mechanisms arranged within the experimental chamber.
