Experimental Research on Technology of Medium Deep Hole Blasting in Large Inclination Rock Diphead Roadway
For improve the efficiency of large inclination diphead excavation, according to the actual construction of field, rock and explosives properties, parameters of smoothing blasting technology for medium deep hole blasting in large inclination rock diphead tunnel is researched, especially improved the blasting parameters of bottom hole and construction technology, present technologies of double bottom hole and casing for disblocking. Experimental study has obtained the good blasting effect, utilization ratio of blasting hole achieved 89.0% on average.
