Integration Techniques of Ecological Restoration and Mining in Open Pit Coal Mine

The ecological environment problems in open pit mining and the present situation of coal mining are analyzed. The traditional open pit mining aims at pursuing economic interests, which leads to serious ecological environment problems. Open pit mining will cause the comprehensive destruction of the solid environment, water body environment, gas environment and ecological environment. Ecological restoration of opencast mine and mining Integration techniques is an effective way to solve the environmental problems of open-pit mine; Ecological restoration become as an important unit of surface mining technology, and the green mining technology system is formed; It is defined that the open-pit mining technology green system and the composition of technology units; We put forward and defined "green degree" concept and the connotation; Through evaluating the green degree index of open-pit mining, the open pit are promoted using a series of integration technologies for ecological restoration and mining, and the green mining goal is realized; The Integration techniques of open-pit mine ecological restoration and mining include two aspect of open-pit lifecycle integration, and ecological restoration progress and stripping progress.
