摘要
通过对锡铁山铅锌矿实验采场中深孔爆破参数的优化,减少二次破碎率,有效的降低了采矿损失率和矿石贫化率,为其他采场的中深孔爆破参数提供可研依据,使得进一步在锡铁山铅锌矿得到推广,并为类似矿山生产提供借鉴。
Through the optimization of the deep hole blasting parameters in the experimental stope of tin Tieshan lead zinc mine,two breakage rates are reduced,the loss rate of mining and the ore dilution rate are reduced effectively,which provides a basis for the middle and deep hole blasting parameters in other stope,which makes further extension of the lead-zinc mine in tin Tieshan and for the production of similar mines.For reference.
