摘要
常规的穿层钻孔预抽煤层瓦斯区域防突措施,抽采瓦斯速度较慢,抽采效果较差,揭煤工期较长,且安全保障程度较低。五阳煤矿扩区进风立井揭煤施工中,运用CO_2气相压裂增透技术,安全高效地揭穿了深厚突出煤层,为同类工程施工提供了经验。
With the regional gas outburst prevention measures with the conventional borehole drilling along pre-drainage seam,the gas drainage speed was slow,the gas drainage effect was poor,the seam opening period was long and the safety guarantee degree was low.In the seam opening construction of the mine air intake shaft of Wuyang Mine,the CO2 gas phase pressurized fracturing and permeability improved technology was applied.The thick and outburst seam was high efficiently and safely opened and passed through and the experiences could be provided to the construction of the similar projects.
