Study on comprehensive water prevention and control for drifting tunnel in Zhongguan ore mine

In order to decreasing drilling holes for exploring water and reducing the risk of water inrush in Zhongguan ore mine,comprehensive advance geology prediction was researched by comprehensive means including ground penetrating radar,infrared detection and advancing hole.Reasonable layout of drill hole and parameter of grouting was determined by research of grouting for stopping up water in water-rich area.Zhongguan ore mine water prevention scheme which include comprehensive advance geology prediction,drilling holes verification and grouting for stopping up water was determined.The results showed that the application of comprehensive water prevention could improve the construction speed obviously and ensuring safety.The scheme could be used in Similar mine with great water.
