摘要
根据桦树沟矿区无底柱分段崩落采矿法放矿方式存在的问题,提出了截止品位与放矿总量控制相结合的新的放矿方式。生产实践表明,截止品位与放矿总量控制相结合放矿有效稳定了采出矿石品位,提高了回采率,延长了矿山服务年限,创造了可观的经济效益和社会效益,可为同类矿山放矿管理提供借鉴作用。
In view of the problem existed in the ore-drawing mode of non-pillar sublevel caving in Huashugou mining area, a new drawing mode was proposed taking into account the cut-off grade and ore-drawing control. Practice showed that, cut-off grade combined with ore-drawing control could ensure consistency in the grade of mined-out ore, resulting in the extraction rate increased, the service life of mine prolonged. This method can create a considerable economical and social senefit, worthy of being referenced in other similar mines.
