摘要
利用控制爆破理论,结合实际情况,研究在复杂环境和复杂地质条件下露天采矿场台阶穿爆参数,以确保紧邻爆区正下方主平硐的安全,永久性公路与高边坡的稳定,降低矿石的贫化率、大块率和采矿成本,提高效益。
In the paper,in terms of the real situation of the open pits,the parameters of drilling and blasting are studied under the complex condition and the complex geological situation in open pits beach by applying controlled blasting, so that it guarantees the safety of the prime tunnel beneath the blasting place,the stability of the lasting road and the high slope, reduces ore dilution rate, lump rate, mining costs, and it brings a better project profit.
