MECHANICS PROPERTIES OF BROKEN ROCK AND ITS APPLICATION IN THE CONTROL FOR SOFT ROCK IN DEEP MINE
破裂岩石的力学性能及在深井软岩控制中的应用

Based on approximating the strength and deformation feature of broken rock, the relationship between support resistance and displacements of surrounding rock is simulated by FLAC3. 3. The degree of support resistance affecting displacements of surrounding rock is analyzed, whose result is contrast with regression result by ANN. It is pointed out that the support resistance has an important effect in the control for soft rock in deep mine and has a sensitive area of action. The engineering practice is carried on in Tiefa mining area,and the soft rock in deep mine is controlled effectively.
