Abstract: Abstract: Based on the theoretical research and field practice of parallel operation mining process of continuous coal mining machine,proposes a balanced mining theory characterized by improving the efficiency of continuous coal mining machine and optimizing the labor organization process.The difference of excavation speed and support speed of roadway is analyzed by the principle of integration,differences in the length of various types of roadways,difference in walking distance of continuous coal mining machine,effect of the Progress of Each Work Point on the Yield of Coal Mining Surface.Determination of parallel working process of working face from the angle of dynamic equilibrium.Field practice shows that the process speed difference of continuous coal mining machine is effectively solved by the balanced mining process.To achieve close integration of processes.The coal mining speed of the working face increased by 10 %.
