Based on the research background of the stability of the heading face in Jinbei Coal Industry Co.,Ltd.,Huozhou Coal Electricity Group,the divided tunneling method and the one-time tunneling method in the tunneling process were discussed,and a dynamic model of the tunneling and support system based on parallel operations was established.In practical engineering,the contact force is stable,and the surrounding rock is in a stable state.The comprehensive mechanized tunneling process improves labor efficiency,reduces costs,and has a positive effect on maintaining the stability of the heading face.
