摘要
针对我矿矿石的本质特性和开采的实际情况,通过改进采面爆破参数和炮眼布置方式,解决了矿石粉矿率高的问题,有效地提高了矿石块度及煅烧矿石的利用率,降低了采矿成本,增加了企业经济效益。
According to the ore nature property and actual mining condition in the mine, the problem of high powder ore ratio is solved by modifying the blasting parameter and the blast - hole arrangement, the lump ore ratio and the ore utilization ratio are increased,thus,the mining cost is reduced and economic profit of the mine is increased.
