Modelling of AT rockbolts parameters for "Soko" underground coal mine

摘要

Research in this article presents development of numerical model of strata interaction with AT (Advanced Technology) roof support in "Soko" deep coal mine and comparison of modelling parameters with results obtained through experimental measurements. Numerical model is based on finite elements method, using Phase2 software. Comparison showed almost complete concurrence, thus justifying introduction of suggested roadway supporting system into the "Soko" underground coal mine.
