露天磷矿山采空区绿色复垦技术研究

以我国最大的露天磷矿开采企业——云南磷化集团有限公司为工程背景,云南磷化集团的磷矿山都分布在高原湖泊滇池的周边,具有较大的生态环境压力。针对在矿区开展生态脆弱区域生态系统功能的恢复重建是企业发展的当务之急这一要求,以该企业所下属的昆阳、晋宁、尖山、海口等4大磷矿山的矿山开采采空区为实际研究对象,围绕绿色矿山建设中环境保护这个基本点,针对露天磷矿山(以云南磷化集团为例)开采与土地复垦等磷资源开发利用的2个环节,重点研究磷矿山土地复垦和生态恢复等关键技术,并将矿山生态恢复的关键技术在云南磷化绿色磷矿山建设过程中进行集成和综合示范。相关的研究成果可为我国磷矿行业的绿色矿山建设提供技术、理论指导和工程示范,对于推动绿色磷矿山建设具有重要的实践和指导意义。

Research on Green Reclamation Technology of the Mined-out Area in Open-air Phosphate Mine

With the largest open-air phosphate mining enterprise-Yunnan Phosphate Chemical Group Co.，LTD（YPCG) as engineering background，all phosphate mines under YPCG are located in the surrounding area of plateau lake Dianchi with great ecological pressure on the environment.It is essential for enterprises to restore and rehabilitate the ecological system functions of the ecological fragile zone in the mining area.With four phosphate mines of Kunyang，Jinning，Jianshan and Haikou under YPCG as research target，environmental protection as the basic point in the green mine construction，key technologies of land reclamation and ecological restoration for phosphate mines are investigated，based on two links of development and utilization of phosphate resources including the mining and land reclamation of open-air phosphate mines（taking YPCG for instance).Besides，these key ecological restoration technologies are integrated and demonstrated in YPCG green mine construction process.Related research achievements could provide technical or theoretical guidance and demonstration projects for the green mine construction of phosphate industry in China，which contributes important practical and instructive significance to promoting green mine construction.
