Abstract：In order to study the application effect of ecological restoration technology in the open-pit coal mine dump of the northern grassland area,this article takes Zhahanao'er Open-pit Mine as the research object,studies the ecological restoration techniques of soil and water conservation,soil improvement and vegetation reconstruction,and monitors and analyzes the restoration effects.The results show that affected by technical measures,vegetation composition,vegetation coverage,plant diversity and plant frequency height are different among different dump sites and monitoring plots.During the six years of ecological restoration,the number of plant species increases from 14 to 47.With the development of ecological restoration,vegetation coverage and plant diversity show an increasing trend.Influenced by site conditions,the frequency and plant height of the same plant in different places are greatly different.The technology of soil and water conservation,soil improvement and vegetation reconstruction adopted in this mining area has achieved good application effect in this mining area,and can be applied in other mining areas in this region.
