摘　　要：CO_2增透预裂技术是一种理念先进、方法安全、效果显著的爆破技术,官地煤矿22610工作面投入使用CO_2增透预裂技术后,对其瓦斯抽放、巷道风流瓦斯等参数进行汇总对比分析,能够更加直观的观察其效果。瓦斯抽采浓度提高,抽采效果明显,保证了矿井的安全生产。CO2 anti-permeability pre-cracking technology is a blasting technology with advanced concept, safe method and remarkable effect. After the 22610 working face of Guandi Coal Mine is put into use with CO_2 antireflection pre-cracking technology, its gas drainage, roadway air flow and gas parameters were collected, compared and analyzed, and its effect can be observed more intuitively. The concentration of gas extraction has been improved, and the extraction effect is obvious, which has ensured the safe production of mine shaft.
