Estimates of vertical tectonic stress in the northwest Ethiopian plateau using topography and gravity data [PDF]

open access: yesHeliyon
The northwest Ethiopian plateau is one of the globe's most complex tectonic zones. Within the area, the previous geological and geophysical investigations revealed volcanism and deformation effects but did not thoroughly examine crust movement, isostatic

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.

Contemporary tectonic stress field in China [PDF]

open access: yesEarthquake Science, 2010
The contemporary tectonic stress field in China is obtained on the basis of Chinese stress field database and Harvard CMT catalogue. Result of the inverted tectonic stresses shows that the maximum principal stress axis strikes nearly north-south direction in the west part of Tibet plateau, ENE direction in North China.

Experimental study on the deformation behaviour, energy evolution law and failure mechanism of tectonic coal subjected to cyclic loads

open access: yesInternational Journal of Mining Science and Technology, 2022
Compared to intact coal, tectonic coal exhibits unique characteristics. The deformation behaviours under cyclic loading with different confining pressures and loading rates are monitored by MTS815 test system, and the mechanical and energy properties are
