众所周知,露天开采的主要优越性在于采矿效率高、成本低。地下开采的主要优点是,良田得以保存,在任何气候条件下,由地下巷道运输矿石的费用较低。用联合开采法开采矿床可扬露天与地下开采之所长,并将其缺点限制到最低程度或者完全排除,从而大大改善技术经济指标,提高开采强度,并保护良田及周围的自然环境。在进行研究工作的基础上,以北部采选公司安诺夫矿床为例,原则制定了露天地下
As we all know, the main advantage of open pit mining is the high efficiency and low cost. The main advantage of underground mining is that fertile fields are preserved and the cost of transporting ore from underground tunnels is lower under any climatic conditions. Exploiting the combined mining method to exploit the deposits can raise the bar of open-pit and underground mining and limit its shortcomings to a minimum or complete extent, thereby greatly improving technical and economic indicators, increasing mining intensity and protecting the fertile fields and the surrounding natural environment. On the basis of the research work, taking the Anov deposit in the northern mining company as an example, the principle of open-air underground
