大采深高水压条件下矿井注浆堵水技术

Water plugging technology of mine grouting under the condition of large mining depth and high water pressure

大采深高水压矿井由于其自身穿透的地下水层多、矿井周围地下水压力大,常常出现突然涌水淹没矿井和采区,造成重大经济损失与人员伤亡,因此常常采取注浆堵水的方法来改善突水情况。本文通过总结注浆堵水技术,方便大采深高水压矿井的注浆设计与施工。本文的研究成果对于金属矿矿井注浆堵水技术的发展有一定参考价值。

The large mining depth and high pressure of mine because of its penetration of aquifers,groundwater around the mine pressure,often appear suddenly gushing water flooded mine and mining area,causing significant economic losses and casualties,so often take the method of grouting to improve the water inrush condition.By summarizing the grouting technology,the grouting design and construction are convenient for the mine with large depth and high water pressure.The research results of this paper have some reference value for the development of grouting and water plugging technology in metal mine.
