江西省主要产煤区煤矸石堆特性研究

摘要

矿山废弃地植被生态重建的主要障碍是废弃地不良的土壤环境，而煤矸石堆该方面问题尤为突出。笔者以煤矸石堆置地为研究对象，分别选取江西10个主要产煤区煤矸石，测定其理化性质、重金属含量。研究结果为江西煤矿废弃地煤矸石堆置地土壤改良和植被恢复提供理论指导。%The main obstacles to ecological revegetation of the mining waste lands are adverse soil conditions and the problems are more conspicuous in coal gangue piles. The coal gangue piles were the research object of this paper. 10 major coal-producing coal gangue in Jiangxi Province were selected, the physicochemical constants and heavy metal content were determined. The results could provide the theoretical basis and guidance for the coal gangue piles soil improvement and vegetation recovery.
