摘　　要：对上海市老港生活垃圾填埋场填埋龄为1～14年的矿化垃圾进行了分选研究。结果表明,填埋龄在8年以上矿化垃圾细料(粒径<50mm)的百分比约占60%,而填埋龄低于5年的矿化垃圾细料比例低于40%。开采出来的垃圾经分选后的产品可得到有效的资源化利用。Landfill mining was considered for recycling of Shanghai Laogang Refuse Landfill. Aged refuse excavated from landfill compartments that have been closed for up to 14 years old was characterized by content and size. Fine particles （〈 50 mm in diameter） accounted for 60% in dry weight for older （〉8 years） refuse but only 40% for less aged samples （〈5 years）. The classification results were discussed based on the changing refuse composition and biodegradation potential. Many reuse options were listed for the classified aged refuse.
