Abstract

According to the reinforcement plan on No.2 main ore-pass of Cheqchao iron mine by the method of support funnel, it is analyzed by numerical simulation that is the stability in the mechanical state of surrounding rock and the local and whole structure before and behind reinforcement, The calculation result presents the theoretical basis for the choice and confirmation of the whole reinforcement plan.
