摘要
针对峰合公司Ⅶ-1封堵不良钻孔出水的问题,采用物钻探相结合的方法找到出水钻孔,制作了相应的封孔装置,利用水泥浆和骨料结合间歇注入的方式,成功封堵了该钻孔,避免了水害事故的发生,确保了矿井安全生产。
Based on the Ⅶ-1 block improper drilling with water in Fenghe Mine,the water drilling position was found with physical and drilling exploration,the corresponding hole sealing device was produced,with the cement and aggregate combination of intermittent injection,successfully the poor block drilling was blocked,avoiding the damage accidents,ensuring the safe mining.
