摘　　要：为确保21609对拉上下工作面合茬后安全回采,开展聚能切缝爆破工艺防治奥灰水技术研究。采用数值模拟与现场实验相结合的方法,对16煤顶板上覆灰岩实施聚能切缝爆破,减少顶板悬顶距离,工作面初次来压步距由45m减小至15m,达到了预期效果。In order to ensure the safe mining of the 21609 pairs of upper and lower working faces after joint stubble,the study on the technology of preventing and controlling ordovician limestone water using concentrated energy fissure cutting and blasting process is carried out.The method of combining numerical simulation and on-site experiment is used to implement concentrated energy fissure cutting and blasting on the overlying limestone of the 16 coal roof,reducing the suspended distance of the roof.The initial pressure step distance of the working face is reduced from 45 m to 15 m,achieving the expected effect.
