In order to reveal the impact of mining in the north piedmont of Qinling Mountain on the ecological environment,combination of on-site investigation and remote sensing interpretation was used in this paper to investigate the geological environment of the mine. The geological environment conditions,the development of geological disasters and the present situation of damage control were selected as the intermediate variables. Each of intermediate variables includes microgeomorphology,hydrogeology,strata lithology;collapse disaster,debris flow disaster;waste slag pressure occupation status,land reclamation status and disaster prevention and control status. The effect of each impact factor was determined by analytic hierarchy process (AHP) and combined with the spatial analysis function of ArcGIS carrying out mine geological environment assessment and map division.The results show that the piedmont of the mountain where the mountain and the platform in the study area are in contact with each other is poor in stratigraphic lithology,and the collapse disaster is serious. The problem of waste slag in the area along the eastern province of 202 is serious and the debris flow disaster is developing.The comprehensive evaluation of the geological environment in the mine area is mostly medium or poor,and the environmental condition along the 202 provincial road is particularly bad. This evaluation result is in good agreement with the field investigation results of the north piedmont of the Qinling Mountain. The evaluation results can provide theoretical basis for the government and other relevant departments to carry out mine geological environment governance and restoration.
