Abstract:

Seabed mining has some technical problems,we particular attention to safety and surface deformation or settlement problems in the mining process.By analyzing the disadvantage of original seabed mining method of Sanshandao gold mine,we propose two kinds of optimum programs for seabed mining,a quasi-rock pulse perturbation outside the lower layer deposition room and pillar filling method and high approach filling method.On the one hand,it can effectively prevent ground subsidence and other problems,on the other hand,through the implementation of the project,the economic benefits of the mine significant growth.Currently,Sanshandao seabed mining conduct below in the -165 m,in the premise of ensuring safety mining,in order to further improve mine productivity,we suggest that using some technical measures,-165~-85 m level orebody of nursing top can be used recovery.
