ALPINE MAGMATIC-METALLOGENIC FORMATIONS OF THE NORTHWESTERN AND CENTRAL DINARIDES
In the paper are presented basic geological, petrologieca1, geochemi-cal and mineral deposit data for five main magmatic-metallogenic formations of the northwestern and central Dinarides: (l)The Permo Triassic rifting related andesite-diorite formations;

ABSTRACT The mechanical properties of shale are key parameters affecting shale reservoirs. They influence the gas content in the shale reservoirs, expansion of hydraulic fractures, and microscopic changes in the in‐situ stress. In this paper, the shale of Longmaxi Formation in Changning area of Sichuan Basin is taken as the research object.

ABSTRACT Isolated overburden grout injection (IOGI) is an economical and efficient green mining technology. During the grout injection process, a large amount of slurry bled water will enter the underlying rock strata below the grouting layer. Under certain conditions, the slurry bled water may seep along the overlying rock layer into the water ...

ABSTRACT During the excavation of a deep‐buried tunnel by the drilling and blasting method, the dynamic stress of blasting may cause the disorderly release of high energy in the rock mass during the blasting process of deep high‐energy rock. Blasting vibration is one of the main factors inducing dynamic disasters (such as rockbursts) in the surrounding
