摘    要:瓦斯抽放是预防煤与瓦斯突出事故最有效的措施之一,而抽放的效果在很大程度上取决于钻孔的封孔质量。聚氨酯封孔法是目前煤矿常用的封孔方法之一,文章通过实验,研究了聚氨酯压注法封孔工艺的封孔效果,该工艺的密封效果较好,值得推广。

关 键 词:瓦斯抽放  聚氨酯  压注法  封孔效果  实验研究

Abstract:The gas drainage is one of the effective measures of preventing coal and gas outburst accident.However,the sealing quality will decide the efficiency of gas drainage largely.Polyurethane sealing process is one of the sealing methods,which is used frequently in coal mine recently.This paper researchs the sealing effect of the polyurethane pressure-injection method by experimental method.The sealing effect of pressure-injection method is better and the method is worth popularization.
Keywords:gas drainage  polyurethane  pressure-injection method  sealing effect  experimental study
