规格较小的构造复杂的贵重金属矿床,在当代采矿技术条件下进行开采,要经常改进其开采工艺。由于贵重金属的价值高昂,对矿藏应特别珍惜,应从矿床中充分采出矿石,并保证质量。目前,对复杂矿床的开采工艺已进行了充分研究。但是,由于贵重金属矿床的埋藏条件、矿体产状及开采技术条件不同,不可能机械地利用其研究成果,应根据每个矿床的具体条件采用最切实有效的开采工艺。为此,在远东北部地区某一个露天矿,曾进行过工业试验,并采用了在矿体接触带形成缓冲层的合理爆破工艺。
Smaller, more complex and complex precious metal deposits are mined under the conditions of contemporary mining technology and their mining processes should be constantly improved. Due to the high value of precious metals, the deposit should be treasured. The ore should be fully recovered from the deposit and its quality guaranteed. At present, the exploitation of complex deposits has been fully studied. However, due to the different burial conditions, orebodies and technical conditions of mining, it is impossible to utilize their research results mechanically. The most effective mining technology should be adopted according to the specific conditions of each deposit. To this end, an open pit mine in the northern Far East has conducted industrial tests and adopted a reasonable blasting process to form a buffer layer at the contact zone of the ore body.
