摘要： 针对玉溪矿东瓦斯抽放巷瓦斯涌出量高、具有突出危险的煤层条件，选用了CO₂气相压裂防突技术进行瓦斯
防突处理。阐述了CO₂气相压裂防突技术的原理，确定了CO₂ 气相压裂防突技术参数———采用直径为50 mm、长度为
2 m的压裂杆；然后在东瓦斯抽放巷布置6 个钻孔，在钻场内布置5 个钻孔进行瓦斯抽采防突；最后进行现场瓦斯浓度
监测。结果表明，采用CO₂气相压裂防突技术解决了东瓦斯抽放巷瓦斯突出危险，保证了工作面的生产安全。

Abstract: In view of the coal seam conditions with high gas emission and outburst risk in the east gas drainage roadway of Yuxi
Coal Mine, CO₂ gas phase fracturing and outburst prevention technology was selected for gas outburst prevention. This paper
expounded the principle of CO₂ gas phase fracturing technology, and determined the technical parameters of CO₂ gas phase
fracturing technology: using a fracturing rod with a diameter of 50 mm and a length of 2 m; then, six boreholes were arranged in
the east gas drainage roadway, five boreholes were arranged in the drilling field for gas drainage and outburst prevention; finally,
on-site gas concentration monitoring was carried out. The results show that the technology of CO₂ gas phase fracturing and outburst
prevention can solve the danger of gas outburst in the east gas drainage roadway and ensure the production safety of the
working face.

Key words: gas drainage roadway; gas phase fracturing; gas outburst prevention
