针对赵庄煤矿一盘区2号和8号煤层的突出危险性的具体情况,通过测定煤层瓦斯压力、煤层原始瓦斯含量、瓦斯吸附常数、孔隙率、坚固性系数和瓦斯放散初速度研究一盘区瓦斯赋存分布规律,对煤层突出危险性进行评估分析,得出2号和8号煤层单项指标部分指标未达到或者超过临界值,瓦斯压力和瓦斯含量均未超过临界值.

For dangerousness of gas outburst of No.2 and No.8 coal seam in Panel 1 in Zhaozhuang mine, the gas occurrence distribution was studied and the dangerousness of outburst was evaluated by measuring gas pressure, original gas content, gas absorption constant, porosity, solid coefficient, and initial speed of diffusion. The results showed that each single index did not reach or surpass the critical value. In addition, the gas pressure and content both did not surpass the critical value.
