强化矿床开采的技术内容非常广泛,本文仅谈谈以下几个主要问题。一、开采方式正确选择开采方式是强化矿山生产的重要条件。世界各国都根据各自的资源特点和技术条件选择开采方式。美国和加拿大的大部分矿床都适合露天开采,因此他们的露天矿都发展很快;瑞典和法国则发展大型地下矿山,其开采强度和经济效果都接近露天矿的指标。从现有的资料看,国外埋藏较浅的矿床
Strengthen the mining technology is very wide, this article only talk about the following major issues. First, the correct choice of mining methods Mining is an important condition to strengthen mine production. All countries in the world choose the mining method according to their own resource characteristics and technical conditions. Most open pit mines in the United States and Canada are suitable for open pit mining, so their opencast mines are growing rapidly; in Sweden and France large underground mines are being developed that are both mining intensive and economically close to the open pit mines. From the existing data, foreign deposits buried shallow
