大宗工业固废用于矿坑回填协同生态修复进展、问题与对策
Progress,problems and countermeasures of bulk industrial solid waste for ecological restoration of abandoned open pits
摘要
Abstract
In China,there are prominent problems such as large generation amounts of bulk industrial solid wastes like tailings,coal gangue,and fly ash,low utilization rates,and a large amount of land is occupied by disorderly stockpiling.At the same time,we are faced with the problem that there are numerous open-pit mining pits in abandoned mines,and the ecological restoration work has a long way to go.On the premise of ensuring that environmental risks are controllable,coupling ecological restoration with the disposal and consumption of solid wastes,and using bulk solid wastes to backfill abandoned mining pits are important links in the construction of a"zero-waste city".The research and application progress of using bulk industrial solid wastes in China for the collaborative ecological restoration of back-filling abandoned pits have been sorted out.The main problems and bottlenecks existing in the implementation process have been analyzed.Finally,optimization suggestions and measures for the comprehensive utilization of bulk industrial solid wastes,such as for ecological restoration,have been put forward,aiming to efficiently promote the construction of a"zero-waste city".关键词
