The study of the influence of elastic modulus of rock and impacted object on impact force is of great significance for the prevention and control of rolling stone hazards.In the laboratory,the process of rock impact was simulated,and the elastic modulus of different rocks and impacted objects were selected as influencing factors to obtain the relationship between the elastic modulus and impact force.The results show that the elastic modulus of the rock and the impacted object is proportional to the impact force,and the effect of the elastic modulus of the rock on the impact force is stronger than that of the elastic modulus of the impacted object,but the difference is not large.According to the test results,the relation formulas of the elastic modulus of the impacted object,the elastic modulus of the rock and the impact force are fitted.
