On green mining technology of surface coal mine

According to the current situation of surface coal mining in China,harmful effects of ecological environment by surface coal mining are discussed,and on the basis of this,the concept of surface coal mine green mining is proposed.the system of surface coal mine green mining is explained from seven aspects:the rationalization of mining technology and equipment selection;the maximization of coal mining recovery rate;the optimization of surface mine transportation system;the digitalization of mining production and operation and management;the comprehensive utilization of resource;the integration of surface mining and ecological environment restoration;the purification of dust and smoke,which is important for the development of coal industry in China.
