针对我国部分有色金属矿山矿床走向长度与延展深度有限,同时生产矿块数受到限制,导致产能受到极大制约,或多中生产运营维护成本、管理难度、安全风险增加等问题,试验成功运用了阶段全孔落矿高效回采技术,通过采用全孔耦合装药、阶段全孔一次落矿,边界空孔减震、V型孔间微差爆破等技术手段,使采场生产能力达到1500t/d以上,实现了安全高效回采。
In view of the limited length and extension depth of some non-ferrous metal ore deposits in China, the production of nuggets is limited, leading to great constraints on production capacity, or more problems in production and operation maintenance costs, management difficulties and increased safety risks. The successful application of the test Stage full hole demineralization recovery technology, through the use of full hole coupling charge, a stage full hole demineralization, boundary hole shock absorption, V-hole between the micro-blasting and other technical means to make the stope production capacity of 1500t / d Above, to achieve a safe and efficient mining.
