To study the influence of pick working angles on cutting performance of auger miner’s aiguille, aiguilles with different pick working angles were developed and their performance were tested on coal cutting test-bed. Cutting performance evaluation system of the aiguille was established first, and then evaluation indexes such as average load, load fluctuation coefficient, and specific energy were analyzed by statistical method. The research indicates that the torque and specific energy of the aiguille decrease first and then increase with increased pick working angles. The feed resistance decreases with the increase in two working angles. The energy consumed by the feed resistance is very small relative to the total energy and can be ignored. When the cutting angle is between 45° and 50° and the tilt angle is about 20°, the torque and specific energy of the aiguille will be at a minimum and the load stability of the aiguille will also be ideal
