Research on Secondary Resource Utilization and Mining Damage Control in Gob-Effect Gypsum Mines

Abstract:

Room-and-pillar mining method plays a dominant role in gypsum mines, which owns a low resource recovery ratio and has left many gobs leading a series of safety production problems to mining enterprises. To get an utmost resource recovery and avoid gob collapse, a secondary utilization scheme has been made by feasibility analysis and theoretical calculation. In this scheme, theoretical calculation about the occurrence conditions of mining damage has been done, and the deep research direction of the mining damage mechanism in gob-effect gypsum mines has been pointed out. This research and its train of thought could provide the gob-effect gypsum mines with reference that would increase ore recovery ratio and prevent mining damage.
