【摘要】 正确判断突水水源与突水构造,合理制定注浆堵水方案,采用定向钻进技术、气动下灰射流搅拌注浆工艺、动水截流等技术快速封堵巷道,并采用引流注浆加固封堵巷道的薄弱地带,利用返流注浆加固陷落柱,既保证了注浆质量,又加快了复矿速度。更多还原

【Abstract】 Base on correct determination of the water inrush sources and water inrush structure, the paper rationally set up the grouting and water sealing scheme. The directional drilling technology, pneumatic cement injection and mixing grouting technology, dynamic water sealing technology and others were applied to rapid sealing of mine roadway. The water diversion grouting technology was applied to seal weak zone of the mine roadway. The returned flow grouting was applied to reinforce the sink hole, which could ensure the grouting quality and reduce the time to recover the mine back to normal coal production.更多还原
