摘要
介绍了东欢坨矿-230m水平大巷注浆堵水技术。采用地面帷幕注浆切断对断层带的补给水源,充填断层带发生冒落形成的空洞,加固断层带及周围岩层,提高围岩强度,形成完整的闭合圈,解除F_2断层对巷道的威胁,恢复管棚巷道,确保矿井安全。
This paper introduced -230m level roadway grouting for blocking up water technique in Donghuantuo mine.Surface grouting curtain was used to cut off the water make-up to fault.Filled the cavity caused by fault zone breaking,strengthened the fault zone and the surrounding rock,improved the strength of surrounding rock,formed closed loop and removed F_2 fault threaten for roadway to ensure mine safety.
