In order to improve perturbation damage caused by opencast mining to the surrounding environment and ecology of mine,based on the green mining concept,from the mining technology itself to consider,the concept of disturbance index of open pit mining was put forward,the theory of disturbance assessment of open-pit mining was established.This theory was used to study the evolution process of the disturbance effect of Heidaigou and Ha'erwusu open-pit mines in 2006—2015.Research results showed the SMDI( Surface Mining Disturbance Index) of the two mines in the last 10 years were greater than zero and the trend was increasing year by year,it was shown that the two mines adopted a number of green mining techniques to enhance the positive effect of mining disturbance and weakened the negative effect of mining disturbance,the open pit was carrying in a green,coordinated and sustainable manner,it also showed that the green mining technology had significant effect on the disturbance of mine production,which can provide some reference for other large opencast coal mines.
