Mining reinforcement viability determination in situ in strong tectonized rock mass using DKRControl method

摘要

An important stage in Romanian uranium industry development consists in decreasing mining support costs. In order to determine the solution viability, for excavation in strong tectonized rock, there was performed DHG type experimental offset at tow uranium mines of National Uranium Company -Suceava Branch. Two monitoring systems provide an important amount of geotechnical information. These data are used for the computation of the mining excavation stability by DKRControl method, to calibrate and validate the numerical model performed in UDEC code.
