The physics of the process of loading of rock mass separated by auger actuators of small diameter is disclosed. Regression dependences of exponential type of power, specific energy consumption of loading as a function of auger working width and speed of machine movement are established. On the basis of the performed experimental and theoretical studies the methodology and mathematical model of optimization of the structure and parameters of shearers under the given mining-geological and mining-technical conditions of operation are developed. It is noted that rational values of geometrical and mode parameters and structure of the shearer will provide growth of technical productivity in 1,1...2,1 times and reduction of power and specific energy consumption of destruction and loading in 1,3...1,5 and 1,3...2,3 times respectively.
