摘要
通过对本煤层瓦斯抽采钻孔漏气机理进行分析,以流体力学、达西定律等为基础,建立钻孔漏气模型,得出了钻孔漏气量计算公式,分析钻孔漏气量影响因素及提高钻孔密封效果的措施,并针对性地提出新型封孔技术,且在现场试验取得成功。
A new technology of plug by analysis the mechanism of gas extraction is put foward, based on the fluid mechanics and the Darcy law,modeled the drilling leakage model,given the formula of the drilling leakage amount,analysis the factors of air leakage and the measures to improve the sealing effect of drilling,and has succeed in the experiment of this field.
