摘要
根据鹤庆锰矿采场回采过程中地压显现的若干现象,探讨了地压活动规律;同时,作为辅助手段用有限元法进行了采场应力和位移的数值分析。得出的结论对于控制地压和采矿生产有指导意义。
The regularity of stope ground-pressure activity in Hegin manganese mine was reseavched based on the ground-pressure phenomenons exhibited during the recovering period. At the same time, the qinit element method was adopted as a additional approadch to analyse the numeric of stope stress and displacement. The result obtained is of importance in guiding the ground-pressure control and mining procties.
