Research on Roadheader in the Large Section Roadway

This paper introduces the situation of the mining equipment, explaines the main composition and structural characteristics of the large section roadway roadheader, designes the main parts that including cutting head,loading mechanism,rotating mechanism and walking mechanism. The whole machine is tested on ground, which shows that this mechanism has the characteristics of strong cutting performance,better stability and reliable performance, as well as has the important functions for improving the mining proportion maladjustment of extra thick coal bed and accelerating competitive mechanization drivage of China.
