| Abstract: | The ore body type of the ⅴ# ore body in Xincheng gold mine is the typical thick broken ore body.Based on the actual situation of the mine,decide to mine the ore body with the pre-roof-controlled upward mediumlength hole sublevel mining with backfill.By the pre-roof-controlling,to ensure the roof and upper wall safety,moreover with the upward medium-length hole mining,mining the ore body safety and efficacy came true. |
