ABSTRACT
Dragline application is an advanced technique for opencast mining, which is integrated with mining, transportation and earth discharge. It can directly discharge the stripping earth into the earth stock yard. This technique enjoys the advantage of large production capacity, cost effective and the shallow-burden opencast mining. This article summarizes the dragline application in Heidaigou Opencast Mine, including the dragline type, the analyses of the mining parameter and cast blast technique and economic and technological analyses, and also introduces the dragline application in Haerwusu Opencast Mine. The two examples witness the availability of the dragline used in Chinese opencast mines and its potential application as well.
