摘　　要：利用采矿废石生产机制砂是节约天然资源、推进砂石行业碳减排的重要途径,但是目前我国尚未建立废石生产机制砂的碳减排核算方法学。本文参照已有固废资源化利用碳减排核算框架,构建了采矿废石生产机制砂碳减排核算方法,涵盖了机制砂生产全生命周期碳排放过程,并利用此方法初步核算了废石替代工艺相较传统矿石开采工艺生产机制砂的节能减排效益,结果表明,废石生产机制砂单位产品节能约7.74 kgec/t,单位产品碳减排量约22.06 kg CO_(2)/t。研究成果可为废石资源化利用减排标准的制定提供参考。The use of mining waste rock to produce manufactured sand is an important way to save natural resources and promote carbon emission reduction in the sand and gravel industry.However,at present,China has not yet deve-loped a carbon emission reduction accounting methodology for waste rock production manufactured sand.Based on the existing carbon emission reduction accounting framework for solid waste resource utilization,this paper constructs a carbon emission reduction accounting method for the production of mechanism sand from mining waste rock,covering the whole life cycle carbon emission process of mechanism sand production,and uses this method to preliminarily calculate the energy-saving and emission reduction benefits of waste rock substitution technology compared to traditional mineral sand mining technology.The results show that the unit product of waste rock production machine-made sand saves about 7.74 kgec/t,and the unit product carbon emission reduction is about 22.06 kg CO_(2)/t.The research results can provide a methodological basis for the formulation of emission reduction standards for the utilization of waste rock resources.
