Abstract: At present, there is a lack of a complete monitoring index system for the monitoring of mine ecological restoration project effect in China. In order to promote the construction of mine ecological restoration monitoring index system, this research builds a set of scientific evaluation index system of mining ecological restoration results monitoring technology from the basic content of mine ecological restoration monitoring, the aspect such as the selection of monitoring indicators research, innovation from water environment, soil environment, the surface environment and geological environment, ecological restoration comprehensive benefit. The index system is applied in the ecological restoration monitoring of a coal mine in Shenmu city, Shaanxi province, and verified by means of GIS analysis and sample monitoring. On this basis, the overall effect of mine ecological restoration is evaluated. The results show that among the soil environmental indicators, the soil layer thickness index reflecting soil physical properties are better. The surface water pollution of the mining area is less, and there is basically no microbial and organic pollution. The water quality is alkaline, which is consistent with the soil in the mining area. The vegetation cover and habitat quality index in the test area are good. The proportion of subsidence area is small. The comprehensive benefit index of mine ecological restoration in the experimental area is not good.
