description The invention provides an anchor rod support design method based on coal mine tunnel surrounding rock aging state information parameters, and relates to the technical field of coal mine tunnel support. According to the method, the surrounding rock strength, the mining influence index, the section size, the section shape, the surrounding rock stability grade, the surrounding rock integrity coefficient, the roadway burial depth, the working face width, the working face advancing length and other stability characteristics of a historical roadway are standardized, and a corresponding standardized parameter set and stability parameter values are formed; the method comprises the following steps: performing support check on a historical roadway by adopting an effective anchoring analysis theory to verify whether the historical roadway has a reference value, if a support scheme of the historical roadway is checked to reach the standard, bringing historical roadway parameters into a roof surrounding rock state informa
