苏联1981～1985年和到1990年的经济和社会发展的主要方针是继续发展井下采煤,其中包括贵重的主焦煤和无烟煤。但大型矿区(包括顿涅茨)的矿山地质条件恶化即开采深度、矿山压力、煤层瓦斯含量、突出和火灾危险、薄及极薄煤层在井下采煤总量中所占的比重都在增加。例如,有73个矿井在800米以上的深度下进行作业。现有的643个矿井中,394个属于超级和三级瓦斯矿井(在顿巴斯有236个),150个矿井有突出倾向的
The main policy of the Soviet Union for economic and social development from 1981 to 1985 and 1990 was the continuous development of underground coal mines, including the expensive main coking coal and anthracite coal. However, the deteriorating geological conditions of mines in large mines, including Donetsk, ie mining depth, mine pressure, coal seam gas content, salient and fire hazards, and the proportion of thin and ultra-thin coal seams in underground coal mines are all increasing. For example, 73 mines operate at a depth of 800 meters or more. Of the 643 existing mines, 394 belong to the super- and tertiary gas mines (236 in Donbass) and 150 are predominantly mined
