Abstract：It is of great significance to analyze the influence of excavation arm structural parameters on the working area in coal mine tunnel excavation.A standard DH method was used to establish the forward kinematics model of the excavation arm,and an improved Monte Carlo method based on Beta distribution was proposed to generate the workspace and working face.This method uses only 20 000 spatial points and achieves higher boundary accuracy than the traditional Monte Carlo method with 100 000 spatial points.Based on the layer cutting method,the boundary space points of the working face were extracted,and the working area was calculated to be 78.86 square meters.By analyzing the influence of the structural parameters of the excavation arm on the working area,it was found that the length of the high-frequency crushing equipment,the amplitude of the crushing bucket teeth,the swing angle of the rotary table,and the pitch angle of the support arm had a significant impact on the working area.By optimizing these parameters,the activity range can be effectively adjusted.
