| 摘 要： | 桦甸市全兴矿业有限公司银龙大理岩矿是露天开采大理岩(方解石)的矿山,但由于传统的爆破方法造成优质矿石在爆破过程中因抛掷碰撞、炮孔内爆轰压力过大而形成粉碎区而使矿石粉碎,落地后被污染而使部分优质的矿石不能被利用,造成资源浪费。为此进行多次中深孔松动控制爆破试验并获得成功,使优质的矿石得到了回收,提高了产品质量,提高资源利用率,降低了生产成本。

| Abstract: | Huadian City Quanxing Silver Dragon Mining Co.,Ltd.is an open-air rock and mineral mining Dali marble （calcite）and mine,but because of the bursting of the traditional method of high-quality ore in the blast caused by the process of collision due to throw,shot hole detonation pressure is too the formation of large crush zone Ershi ore crushing, after landing some high-quality ore Ershi pollution can not be used,resulting in waste of resources.To this end several times in the loose control of blasting hole successfully tested,so that high-quality ore has been recovered,improved product quality,improve resource utilization,reduced production costs. |
