Abstract: Zhe paper proposed zhe concept of coal pipeline in open-pit mine In view of drawbacks of zhe coal way in opencast mine and development of pipelines transporting coal technology In the domestic. Feasibility analysis of surface coal mine pit pipeline from zhe aspects of Internal drainage effects、effects of surface mine blasting to high wall roadway、water problems of pit coal pipeline pulping and Economic issues. Coming to the conclusionthe pit coal conveying pipeline in technically feasible, but its economy is not obvious. If open-pit mining coal transport over long distances or downstream users required products are mainly coal chemical projects of raw coal, the coal pipeline in open-pit mine obvious advantages, is worth promoting.
