普罗科彼耶夫斯克煤田是为库兹巴斯、乌拉尔和其他地区的冶金企业提供炼焦煤的主要基地。但近年来随地质条件变化复杂,降低了开采量,实际上没有提高劳动效率,反而增加了采煤成本。普罗科彼耶夫斯克各矿井历年所获得的技术经济指标列入表1。 The Prokopjevsk coal field is the main site for supplying coking coal to the metallurgical enterprises in Kuzbass, the Ural and other regions. However, with the complicated geological conditions in recent years, the amount of extraction has been reduced. In fact, the labor efficiency has not been increased, but the cost of mining has been increased. The technical and economic indicators obtained over the years in the various Prokopjevsk mines are shown in Table 1.
