摘要
为解决低透气性煤层较难抽采的难题,赵庄矿南苏风井揭煤应用二氧化碳爆破技术来增加煤层透气性,提高瓦斯抽采效果,试验证明了该技术在煤层卸压增透中具有快速、高效、安全的优点,为二氧化碳爆破增透技术在低透气性煤层强化抽采的推广应用提供了参考和经验。
To solve the problem of low permeability coal seam are harder to extraction,the South Sufeng Shaft uncovering mining used carbon dioxide blasting technology to increase coal seam permeability,improve the effect of the gas extraction in Zhaozhuang Coal Mine,the test proved that the technology pressure relief in the anti- reflection has the advantages of rapid,efficient,safe for carbon dioxide blasting anti- reflection technology in low permeability coal seam extraction provides reference and experience for popularization and application on coal seam.
