The mechanism of cutting process of roadheader with cutting head was researched, and the influences of properties of coal and rock on cutting load were deeply analyzed. Aimed at the defects of traditional calculation method of cutting load on fully expressing the complex cutting process of cutting head, the method of finite element simulation was proposed to simulate the dynamic cutting process.

Roadheader machines are widely used. China''s roadheader market has a promising future, and its market demand is huge. We analyze it from two aspects: coal mine roadheader and tunnel roadheader: First, the prospect of coal mining machine market. China is a large coal producing country with numerous coal mines of various sizes.

The roadheader does require a greater investment than an excavator with a roadheader attachment. The excavator''s performance, however, is limited because it is dependent on the hydraulic power capabilities of the excavator. Attachments are extremely flexible in large tunnels for scaling, cutting manholes, corners and excessive grouting.
