Keywords: roadheader, artificial neural networks, rocks properties, control system 1. Introduction Use of nonrenewable source of energy such as coal requires more and more difficult conditions of mining. Polish coal mines extract coal from deep seams what means difficult miningandgeological and environmental conditions.
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.
