该论文调查瓦斯突出的持续时间、突出量及突出空间大小的相互关系,从而根据这些资料来推定瓦斯突出破坏面的移动速度。 首先,笔者统计、分析了1972年～1977年在苏联顿巴斯发生煤层瓦斯突出的资料中38起事例,求出了瓦斯突出持续时间T(秒)和瓦斯突出量A的关系:T=1.5A~(0.6)。这种情形下的相关系数为0.82。且同样地能够求出在顿巴斯砂岩层的瓦斯突出的这种关系:T=0.15A~(0.6)。
This paper investigates the relationship between the duration of gas outburst, the amount of outburst and the size of the outburst space, and based on these data, estimates the moving speed of gas outbursts. First, the author statistically analyzed 38 cases of gas outburst in the coal seams from 1972 to 1977 in Sudan, and found the relationship between the duration of gas outburst T (seconds) and gas outburst A: T = 1.5 A ~ (0.6). The correlation coefficient in this case is 0.82. Likewise, the relationship between gas outbursts at the Donbas sandstone can be found: T = 0.15A ~ (0.6).
