摘要
露天坑的巨大废弃空间本身是一种资源,在不影响采矿安全生产的前提下,利用露天坑空间及其区位优势条件,将其作为城市大宗固废回填消纳场所是城市固废减量化、资源化、无害化利用的新途径。本文探讨了大型露天坑生态修复固废回填工艺,对比了湿式高浓度固废回填与干式固废碾压回填工艺,对露天坑回填过程中相关安全及环境问题进行了探讨分析。研究表明,利用城市固废回填进行生态修复,既能消除矿山地质灾害隐患,又能助力城市大宗固体废物减量化发展,具有良好的经济效益和社会效益。
The huge waste space of open pit itself is a kind of resource.On the premise of not affecting mining safety production,using the open pit space and its location advantages as a place for the backfilling and consumption of urban bulk solid waste is a new way for the reduction,recycling and harmless utilization of urban solid waste.This paper discusses the solid waste backfilling process for ecological restoration of large open pit,compares the wet high concentration solid waste backfilling process with the dry solid waste rolling backfilling process,and discusses and analyzes the relevant safety and environmental problems in the process of open pit backfilling.
