Abstract: In view of the investigation on the current situation of open-pit mine dumps in northern China, the common problems in
the ecological restoration process of waste dump were systematically summarized. In view of the characteristics of poor soil quality and
water retention of waste dumps, this paper systematically put forward the ecological restoration technologies such as surface soil
quality conservation, slope optimization, soil improvement, optimal allocation of vegetation, water-saving irrigation, etc., so as to
form a set of ecological restoration technologies suitable for ecological restoration of waste dumps in northern China.

Key words: waste dump; ecological restoration; open-pit mine
