Abstract: Limestone，as an indispensable raw material in construction and chemical industries，has a tremendous market demand，however，abandoned quarry causes serious damage to the mining district and its surrounding ecological environment. Hence，it is an effective way to build green mines that carrying out the research work of ecological restoration technology of abandoned quarries.On the basis of collecting relative information at home and abroad，the ecological restoration technologies of rock slope，working platform，pit bottom，mine road，industrial square，dump，and the surrounding area of mining boundary were summarized，and the advantages and disadvantages of the main ecological restoration techniques of rock slope and dump were analyed emphatically. In the future，the following studying contents should be strengthened: development of low-cost plant growing medium，mechanism of synergetic coupling regulation of plant growing medium-root growth， overall stability mechanism of fissured rock mass-root-plant growing medium on slope surface，crack monitoring and control and vegetation allocation mode in the dump，water-conserving and timely irrigation and maintenance technology in mining area based on 5G technology，etc..To overcome the shortcomings of traditional monitoring technology，which is difficult to achieve multi-channel and whole area coverage，5G technology，GIS and RS should be effectively combined.With the support of artificial intelligence（AI）technology，real-time dynamic monitoring should be carried out on the site conditions，soil moisture，timely irrigation and maintenance system working status，plant growth status and other aspects of the mining area， then，based on this，the restoration effect may be evaluated to achieve ecology construction of dynamic monitoring and evaluation index system of restoration integration.
