The Effect of a Tectonic Stress Field on Coal and Gas Outbursts [PDF]

open access: yesThe Scientific World Journal, 2014
Coal and gas outbursts have always been a serious threat to the safe and efficient mining of coal resources. Ground stress (especially the tectonic stress) has a notable effect on the occurrence and distribution of outbursts in the field practice.

Tectonic evolution and mineralization exploration of Lujing uranium ore field, South China [PDF]

open access: yesScientific Reports
Granite-type uranium deposit is one of the most important uranium deposit types in China, with orebodies strongly controlled by structures. Previous studies of the Lujing ore field mainly focused on metallogenic genesis and Yanshanian structure, which ...

Study of in situ stress inversion of deeply incised valleys considering the river evolution process [PDF]

open access: yesScientific Reports
The study of the in situ stress field is significant for the stability of large underground caverns near deep V-shaped valleys. Tectonic movements, gravity and river erosion have a great influence on the formation of the modern stress field.

The recent tectonic stress field of the Amur region

open access: yesГеодинамика и тектонофизика, 2018
The Amur region (Priamurie) is located in the NE part of the Amur lithospheric plate and its surrounding territories. Seismic activity is moderate in Priamurie, and the regional earthquakes, including the strongest ones, occur mainly in three seismic ...
