Analytical modeling of the backfill massif deformations around the chamber with mining depth increase
(CRC: Press, 2015)
Using thermodynamic analytical research method, the investigation of strains formation in the backfill massif around the chamber of second stage was performed. It was established that the horizontal and vertical dimensions ...
RATIONALIZATION OF DEEP BOREHOLES DRILLING IN THE CONDITIONS OF PJSC “ZAPORIZSKYI IRON-ORE PLANT”
Purpose. To develop effective approach to determination of parameters of deep boreholes location which would consider stress of the ore massif in the course of layers breaking. Methods. It has been established that energy ...
