采场集中打眼集中爆破回采工艺

Process of Concentrated Drilling and Blasting in Stoping

为了更好安全回采采场,提高采场回采效率,凡口铅锌矿不断探索高效安全的采场回采工艺,其中比较重要的一项就是集中打孔集中爆破工艺.该工艺减少松石次数,也减少了采场找边、切采及挑顶作业的循环环节,各项作业专业化,缩短施工时间,提高劳动效率,降低安全风险.

Fankou Lead-zinc Mine has kept on exploring high efficient and safety stoping processes in order to have moresafety stoping and improve the efficiency of mining, one of which is concentrated drilling and blasting. The technology cannot only decrease the times of the hoard of processing for stope, but also reduce circulation links of the stoping for edge andmining cross. The each operation is specialized, the construction time is shortened, labor efficiency is improved, and thesafety risks are reduced.
