Method for accurately calculating impact resistance of coal mine tunnel

The invention provides a method for accurately calculating the impact resistance of a coal mine tunnel. The method comprises the following steps: performing a dynamic load impact test on materials taken from each supporting member on site, determining detailed contents such as the materials, experimental equipment and a loading mode in the test, obtaining a real impact resistance value, and performing weight distribution on energy which can be absorbed by each supporting member of a top plate and a side part and a pressure relief hole according to the stability condition of surrounding rock, wherein the basic data source is real and effective, and the energy calculation method is scientific and reasonable; providing a specific calculation formula of the energy absorbed by the pressure relief hole, performing comprehensive weighted calculation on the impact resistance of a pressure relief measure according to the condition of the surrounding rock, and comprehensively considering the influence relationship of t
