Abstract: Compared with the traditional quarries which aim at obtaining mineral products,the stone mines supporting for construction projects have the characteristics of complex surroundings,high construction intensity,short life cycle,flexible and changeable engineering quality requirements,and large workload of blasting safety alert.Based on the example of the blasting mining in Cosco Shipyard Phase II project stone mine in Putuo Liuheng Island,introduced the key points of the design and construction technology and the construction experience of this kind of mine blasting.The existing problems of the mining blasting practice in complex environment in small stone mines supporting for constructin projects,besides that,the above discussion results can provide some reliable reference for the similar engineering practices.

Key words: Complex surroundings,Blasting,Construction technique
