摘要
为提高三山岛金矿采场回采效率,缩短采场回采的时间,经过研究矿山采用宽进路交替式盘区耦合开采技术,一步进路回采后接顶充填,二步进路回采后预留切割槽,为接续盘区的回采提供了空间。该技术满足了扩产要求,具有推广应用价值。
In order to increase the mining efficiency and shorten the stope mining time, the wide drift alternate panel coupled mining technology is adopted subject to discussions. The roof-contact filling is conducted after one-step drift stoping and cutting slot is reserved after two- step drift stoping to provide space for mining in splicing panel. Being able to satisfy the production expansion, this technology has popularization and application value.
