摘　　要：为取出突出煤层的完整煤芯,使用初始释放瓦斯膨胀能指标对煤层进行突出危险性预测,本文以单动双管取芯器为例,对井下突出煤层取芯工艺进行研究。In order to take out the core of outburst coal seams, and use the index of methane expansion energy initially released to forecast the fatalness of outburst, the paper analyzes the underground coring technology based on swivel type double tube core barrel.

关 键 词：取芯工艺 初始释放瓦斯膨胀能 突出预测 单动双管取芯器
