顿巴斯矿井防止煤和瓦斯突出的问题,是煤炭工业最重要的科学技术问题之一。 在战后顿巴斯煤炭工业迅速发展期间,这一问题的迫切性特别增强了。 随着煤炭开采的发展,采掘深度和开采的突出危险煤层数量不断地增加。例如,从1946年到1980年,采掘深度增加了400～450米,有煤和瓦斯突出倾向的煤层数目增加到5.3倍左右,而这些煤层的平均年产量增加 The Donbass mine is one of the most important scientific and technological issues in the coal industry to prevent coal and gas outburst. The urgency of this issue has been particularly enhanced during the post-war Donbass coal industry’s rapid development. With the development of coal mining, the number of extraordinarily dangerous layers of excavation and mining has continuously increased. For example, from 1946 to 1980, the depth of excavation increased by 400 to 450 meters and the number of coal and gas-prone coal seams increased to about 5.3 times, while the average annual production of these seams increased
