摘要
为了有效预防煤与瓦斯突出,通过对何庄矿煤层瓦斯压力及瓦斯含量、瓦斯放散初速度、煤的坚固性系数、构造煤发育情况及瓦斯动力现象等参数的分析,提出采用瓦斯参数结合瓦斯地质分析法对矿井二1煤层进行煤与瓦斯区域突出危险性预测。预测结果表明:二1煤层在埋深388 m以深的区域划为突出危险区域,构造煤是控制何庄矿煤与瓦斯突出的主要因素。
To control the coal and gas outburst disaster effectively,based on the analysis of gas pressure as well as gas content,the initial speed of the gas emission, the hardness coefficient of seam, the development situation of tectonic coal, the gas dynamic phenomenon and other gas parameters in the coal seam of Hezhuang Coal Mine,the gas parameters combination gas geology statistics method was applied to the regional prediction of the coal and gas outburst for Ⅱ1 coal seam. The prediction results shows that the [1j coal seam deeper than 388 m would be dangerous,tectonic coal is the main factor of controlling coal and gas outburst in Hezhuang Coal Mine.
