| Abstract: | After the finish of open pit mining in Cangshang mining area of Sanshandao gold mine,little segment caving mining method without sill pillar is carried out to make use of the low-grade medium-thick cracking gold orebody in the open pit bottom.By choosing suitable stoping method,sublevel height,blasting parameters and related technical measures,the low-grade gold orebody in the open pit bottom is recovered efficiently.Meanwhile,good economic results are achieved. |
