摘　　要：提出采用绿色开采技术是解决露天矿生态环境问题的根本途径,在原有工艺环节基础上加入"生态恢复"环节,形成露天煤矿绿色开工艺系统。对生态恢复环节的作业方式和参数等进行研究,定义了生态恢复作业面、土地平整带等概念。土地平整带的划分方式按与排土台阶的关系分为:平行划分和垂直划分。生态恢复环节主要作业参数为:生态恢复作业面的面积、土地平整带宽度、土地恢复工作线长度、平均填方厚度或挖方深度(填方为正、挖方为负)、土地恢复水平跟进速度,建立了作业参数计算的数学模型,确定了生态恢复环节的设备类型及其生产能力计算方法。以准格尔黑岱沟露天煤矿内排土场土地恢复为例进行了设计,确定了土地恢复工作面的划分、生态恢复环节工艺及设备类型,确定了作业参数。Green mining technology is a fundamental way to solve the problems of ecological environment in open pit mines.On the basis of original technological processes,adding the process of ＂ecological restoration＂to form a green technology system of open pit coal mine. This study investigated on the operation mode and parameters of ecological restoration,and defined the concept of ecological restoration work surface,land leveling belts and so on. According to the division of land leveling belts and dump bench,the land leveling belts are divided into parallel division and vertical division.The main operating parameters of ecological restoration process are ecological restoration work surface area,land leveling land restoration work belt width,work line length,the average thickness of fill or excavation depth（ fill is positive,cut is negative）,and land restoration level speed.The mathematical model of the calculation of operating parameters is established.Equipment type of ecological restoration process and calculation method of production capacity are determined.As an example,the Zhungeer Heidaigou Open-pit Coal Mine Dump in land restoration is designed.The division of land restoration working surface,the process and equipment types of ecological restoration and the operation parameters are determined.
