露天采煤的意义在苏联正在逐年提高,1957年露天煤矿煤产量估总产量的五分之一.今后数年内,露天煤产量的提高不仅依靠旧有煤田的发展,而且要靠新区露天矿的建设.现在,在苏联的领域内发现一些适合露天开采的煤田,储量约为七百亿吨,其中A_2十B十C_1和C_2级的储量,据1957年1月1日统计,占二百五十亿吨.在这些煤田内可建二百五十个左右的露天煤矿,总的年生产能力可达六亿吨.
The significance of open pit mining in the USSR is increasing year by year, accounting for one-fifth of the total output of open-pit coal mines in 1957. The increase in open-pit coal production in the next few years depends not only on the development of old coal mines but also on the open pit mines of the New District Now some coal fields suitable for surface mining in the Soviet Union are found, with a reserve of about 70 billion tons, of which A_2 to B10 C_1 and C_2, according to statistics of January 1, 1957, amounting to two hundred and five One hundred million tons of open coal mines can be built in these coal fields with a total annual capacity of up to 600 million tons.
