The paper introduces the remnant ore pillar stoping practice with the open stope method and manage-ment status of stope roof in gold mines of China. The feasibility to replace ore pillar with concrete artificial pillar is an-alyzed. Combining with the remnant ore pillar stoping conditions in Jinfeng gold mine, the concrete artificial pillars are designed and constructed. The replacement practice reveals that not only the limited resources can be made full use of, but also the stability of goal can be ensured. Accordingly, the economic benefits are enhanced and'the service life of the mine is extended.
