| 摘 要： | 新建矿井瓦斯资料缺乏,尤其是瓦斯含量与瓦斯压力数据。基于新建矿井勘探期间勘探钻孔取得的煤样,利用勘探钻孔煤芯解吸法测定了煤层瓦斯含量等参数,依据计算煤层瓦斯含量的朗格缪尔方程,推导出原始煤层瓦斯压力。根据计算得到的煤层瓦斯压力及周边生产矿井资料,对宝达煤矿K2煤层煤与瓦斯突出危险性进行了评估。

| Abstract: | New mine is lack of gas data,especially the gas content and gas pressure data.Based on the coal samples which were obtained during the exploration of the new mine exploration drillings,the coal seam gas content determined by using exploration drilling coal core desorption.According to the gas content calculation of Langmiur equations,gas pressure in the original coal seam is deduced.According to the calculated coal seam gas pressure and the surrounding mine production data,is K2 seam of Baoda coal mine about coal and gas outburst risk is evaluated. |
