工程配套小型石料矿山复杂环境开采爆破技术

建设工程配套石料矿山相比传统以取得矿产品为目的的采石场具有周边环境复杂、施工强度高、全寿命周期短、工程质量要求灵活多变、爆破安全警戒工作量大等特点。以普陀区六横岛中远船务二期工程石料（宕渣）矿爆破开采工程为例，介绍了该类矿山开采爆破的设计施工技术要点及施工经验，有效解决了建设工程配套小型石料矿山复杂环境开采爆破存在的一些问题，对于类似工程实践有一定的借鉴价值。

Mining Blasting Technique in Complex Environment in Small Stone Mines Supporting for Construction Projects

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.
