在1976～1983年期间,苏联煤炭工业部和苏联国家采矿技术监察委员会批准了两个规程细则和附件,详细规定了煤层突出危险性的日常预测方法。在第一个规程细则中,瓦斯涌出的临界初速度值qk=5升/分,它与煤的变质程度和煤层的开采深度H无关。在附件和第二个规程细则中,当挥发分分别为V~(daf)<15％;15～20％;20～30％;和30％以上且煤层开采深度H小于800米(准备巷道)或小于1000米(回采工作面)时,qk分别等于
Between 1976 and 1983, the Ministry of Coal Industry of the Soviet Union and the Soviet Union’s National Mining and Technical Supervision Commission approved two rules and annexes detailing the daily forecasting method for the prominent danger of coal seams. In the first protocol, the critical initial velocity of gas emission, qk = 5 liters / min, is irrelevant to the degree of coal metamorphism and the depth of coal mining. In the annex and the second protocol, when the volatiles are respectively V daf 15%, 15% -20%, 20% to 30%, and the depth of coal seam exploitation H is less than 800 meters (preparation of roadway) Or less than 1000 meters (mining face), qk equal to
