Finite element method applied in mine pressure computation within the context of rock massif – support system interaction 

Toderaş, M; Moraru, R; Danciu, C (National Mining University, 2019-03-30)
Purpose. The analysis of the current underground mine workings, both those that are in operation and works located within the mining perimeters where activity was stopped, is leading directly to the problem of stability, ...

The effect of increasing the water content on rocks characteristics from Şuior, Romania 

Toderas, M; Moraru, R (National Mining University, 2017-09-30)
Purpose. Generation of relative humidity fluctuations lead to a further decrease in the resistance of rocks, which involves the swift evacuation of groundwater from mining works. For andesitic rocks strongly hydrothermal ...
