摘要：

With　the　development　of　science　and　technology　and　industry　level,　solid　wastes　are　fully　utilized.　Among　which　gangue　is　the　solid　waste　generated　in　the　process　of　coal　mining,　its　comprehensive　utilization　rate　is　more　than　60%.　Environmental　pollution　in　the　process　of　coal　mining　is　one　of　the　typical　environmental　problems　confronted　in　China.　In　this　paper,　the　life　cycle　inventory　(LCI)　of　gangue　was　acquired　by　the　method　of　life　cycle　assessment　and　further　environmental　impact　assessment　was　achieved　as　well.　The　results　showed　that　environmental　impacts　based　on　allocation　of　calorific　value　were　greater　than　that　of　economic　value,　and　it’s　about　3.68　times　the　impacts　assigned　by　economic　value.　Therefore　allocation　of　economic　value　was　better.　©　(2015)　Trans　Tech　Publications,　Switzerland.
