煤与瓦斯突出是不稳定煤体突然像雪崩一样脱离煤层和瓦斯涌入坑道的现象。突出的防治问题不仅对苏联,而且对大多数采煤国家都有非常现实的意义。煤与瓦斯突出现象是一种自然-工艺现象。它由自然条件所决定,是人们采用不正确的采掘作业工艺所激发出的。为了展现我国东部地区煤与瓦斯突出防治问题的解决前景,首先应当把该地区同顿巴斯的突出危险性相比较,从而估计该地区的突出危险现状。在顿巴斯,由于采深大,乍看存在着煤层越簿,突出危险性越大的反常规律,突出问题是非常尖锐的。
Outburst of coal and gas is a phenomenon in which unstable coal suddenly breaks away from the coal seam and gas influx into the tunnel like an avalanche. Outstanding prevention and control problems have very real significance not only for the Soviet Union but also for most coal mining countries. Coal and gas outburst is a natural phenomenon. It is determined by natural conditions, inspired by people using improper mining operations. In order to show the prospect of solving the coal and gas outburst prevention and control problems in the eastern part of our country, we should first compare the prominent danger with that of the Bund in the area so as to estimate the prominent dangerous situation in the area. At Donbass, the salient issues are acute because of deep mining and at first glance the existence of an overburden of coal and highlighting the anomalous laws of greater danger.
